Transcription (genetics), the process of copying DNA to RNA by an enzyme called RNA polymerase (RNAP) \nTranscription is the process through which a DNA sequence is enzymatically copied by an RNA polymerase to produce a complementary RNA. Or, in other words, the transfer of genetic information from DNA into RNA. In the case of protein-encoding DNA, transcription is the beginning of the process that ultimately leads to the translation of the genetic code (via the mRNA intermediate) into a functional peptide or protein. Transcription has some proofreading mechanisms, but they are fewer and less effective than the controls for DNA; therefore, transcription has a lower copying fidelity than DNA replication.\n\nLike DNA replication, transcription proceeds in the 5' → 3' direction (ie the old polymer is read in the 3' → 5' direction and the new, complementary fragments are generated in the 5' → 3' direction). Transcription is divided into 3 stages: initiation, elongation and termination.\n\nclick here:http://en.wikipedia.org/wiki/Transcription_%28genetics%29#Prokaryotic_transcription

do you mean what processes cells must undergo? \n\nIf that's your question, then the processes would be cell division by mitosis (to produce more cells, so that organism can increase in size/length), cell elongation(this occurs mainly in plants via vacuolation and thus aids in increase in size and length) and cell differentiation(this allows genes to be switched on or off so that certain traits/phenotypes can be expressed, eg. gene that codes for blue eyes switched on for cell in the eye and not elsewhere like cell on the hand/feet). Hope this answers your question.

Hello,\nUsually in Eukaryotes, mRNAs-after transcription- get attached to proteins in the ratio \n            mRNA : Protein = 1 : 3 \nThese complexes of mRNA and protein r called informosomes which are very stable. Usually mRNAs get destroyed immediately after translation but informosomes can survive for about 4 weeks!\nHope this information is sufficient

The answer is B\n\nA. Transcription always occurs in the nucleus (in eukaryotes) because transcription uses an RNA polymerase to copy the DNA which is inside the nucleus. Translation is done in the endoplasmic reticulum by ribosomes which read the mRNA (the product of transcription) to produce proteins.\n\nB. Both Transcription and Translation require complementary pairing, thats the whole point.\n\nC. Transcription involves polymerizing nucleotides and translation polymerizes amino acids\n\nD. Translation occurs in ribosomes, transcription from above occurs in the nucleus.\n\nE. Transcription involves RNA polymerase, and translation does not :)

Protein synthesis is not the simplest process, but I will try to keep this answer as simple as possible.  Here I present a highly simplified reduction of the process of protein synthesis.\n\nmRNA made in the nucleus of a cell is transported to the cytoplasm of a cell.  When mRNA is in the cytoplasm the ribosome assembles around it.  The ribosome is composed of two subunits, a small ribosomal subunit and a large ribosomal subunit.  Each of the subunits is composed of rRNA and proteins.  The two ribosomal subunits will bind to the ribosome binding site (rbs) of the mRNA.  The rbs is located prior to the open reading frame of the ribosome. When the ribosome binds to the mRNA the ribosome begins to move down the mRNA.  \n\nDuring this time tRNA is binding to the mRNA as well.  tRNA simply carries the amino acid that will compose the protein to the mRNA so that the amino acids of the protein can become bound to one another.  \n\nSo as the ribosome moves down the mRNA it will encounter tRNA.  However, the tRNA's amino acids will not be bound together until the ribosome reads a mRNA sequeunce that indicates an open reading frame is present. An open reading frame is the sequence of mRNA that is translated into protein sequence.  So once an open readin frame is indicated to be present the ribosome moves down the mRNA until it reaches the start codon.  Protein synthesis begins at hte start codon.  At the start codon the tRNA specifying methionine is present.  Methionine will be the first amino acid in any protein because the methionine codon is also the start codon.  So the methionine tRNA will move into the A site.  At this site the ribosome will ensure that the correct tRNA is bound to mRNA.  If the correct tRNA is bound then the ribosome A site moves onto the next codon and the tRNA just found to be correct will move into the P-site, in this case the methionine tRNA will move into the P-site.  The tRNA that just moved into the A-site will now be checked to see if it is the correct tRNA.  When the tRNA is found to be correct then the amino acid on the tRNA in the p-site will form a peptide bond with the amino acid on the tRNA from the a-site. The amino acid chain is connected to the tRNA in the a-site as the amino acid that was connected to the p-site tRNA becomes disconnected as it forms a peptide bond with the a-site tRNA's amino acid. Then the ribosome moves down the mRNA again.  The tRNA from the p-site moves to the e-site and it is allowed to exit the ribosome.  The p-site and a-site perform the same function as before and the peptide chain will get longer until the ribosome reaches a stop codon.  Once the ribosome reaches a stop codon the peptide chain will no longer increase in size.  The ribosome will then move until it finds another start codon or until the mRNA sequence indicates that it should dissociate.

In the nucleus of your cells.  This transcribes mRNA from your DNA and thus must be in the nucleus.

transcriptional control\n\ntranscription factors are the key regulators of which genes are expressed in cells. transcriptional control in the various differentiated cell types allows each type of cell like epithelial, muscle or neuron to express different amounts of the possible proteins. thus, eventually developing into specialized organs with specific roles and functions.

The answer above is wrong- RNA polymerase is an enzyme involved in transcription. \n\nThe polymers made are:\n\nDNA in DNA replication\n\nRNA in DNA transcription

first of all proteins  are  synthesized by the  combination of many things on the  ribosomes in the  cytoplasm not  in the  DNA\nit is  a very complicated process but here is  a simplification of it:\nA)translation---->\n1-DNA double strand opens up by a  certain specific molicule (like  unzipping the DNA) this is  controled by an initiator and inhibitor and so many other molecules due to the dec or inc of certain specific molecule in the cells\n2-RNA single strand is formed over one of the double strand DNA (G-C A-T or U) ending up in what we call messenger-RNA this mRNA separates from the original DNA strand by a very complicated process involving so many  chemical  molecules  and  leaves the nuclease through pores in the nuclear membrane\nB)transcription--->\n1-the mRNA reaches to ribosomes either on the Endoplasmic reticular systems outer surface or free in the cytoplasm(ribosomes are composed of two protein subunits one big  and one small) the mRNA incers inside between  the two parts of ribosomes \n2- ribosomes start reading the mRNA as Codones (triple sequences) like ACG-AUC-CUA-AAA\n3- for each codon sequence there is  a specific molecule in the cytoplasm that called transcription-RNA which attaches one codon from one specific codon from one side and one specific amino acid from the other side \n4-so at this stage we find  a sandich of aminoacids on top tRNA in the middle and mRNA on the other side\n5- finally these amino acids will all connected togather and separat from the ribosome and the sandwich \nNOTE: so actually every single codon has a single part of tRNA that will specificly attach to it and attach  a specific amino acid from the other  end and thats what they meant by discovering the human genome (knowing each  codon goes with what  part of tRNA and each part of tRNA goes with what amino acid\nC)modification---->\n1-now the protein is a  simple sequence of amino acids with no 3 dimentional structure \n2-modification is  a whole  very  complicated process that cant be writen in here but it involves golgi aparatus smooth endoplasmic reticulum and rough endoplasmic reticulum\nFINITO

once the DNA has been transcribed, spliced and modified, the new mRNA is moved out of the nucleus of the cell and into the cytoplasm.  There, a ribosome attaches to it.  The mRNA serves as a template for translation.\n\nHere's how that works.  mRNA is read in groups of 3 nucleotieds.  Each group of 3 is called a codon.  When the ribosome is attached to the mRNA, new amino acids that correspond to the codon can get added to the chain.\n\nEssentially, the ribosome moves like a train down the mRNA, stopping at each codon.  Every time it stops, a tRNA can enter and drop off an amino acid.  The tRNA has to be specific to that codon otherwise, it can't enter the ribosome.  The tRNA that is specific to a certain codon, is also specific to the amino acid it carries.  So indirectly, each codon corresponds to an amino acid.\n\nThe role that DNA plays is that it encodes for the mRNA and the mRNA encodes for the protein.\n\nThere's a lot of nuance that I didn't get to, like anticodons, reading frames, P sites, A sites, E sites, etc...If you care about these specifics, post another question ;p

As you know, mRNA has copied the protein-making instructions from the DNA. Well, tRNA brings the required amino acids to build the primary structure of the protein, as is stated by the instructions on the mRNA.

A promoter is a sequence of DNA, upfield of the area that is going to be transcribed that helps the RNA polymerase recognize and bind to the template DNA strand.  Transcription factors recognize these promoter sequences and bind to them, allowing RNA polymerase to interact with the DNA strand.  An example of this is the TATA box, a eukaryotic promoter that has a TATAAT consensus sequence.  The TATA Binding Protein is the first transcription factor to bind this, followed by several other TFIIs which bring in and align RNA polymerase II.  To draw this, draw the TATA box 30 bases upfield (to the left) of where transcription will intitiate.

dont really get yr question. do u mean reverse transcription? mail me at youngatheart_tapan@yahoo.co.in. i'd be glad to help.

The statement is true. If you assume that takeing dna to rna is the same language, then that would be transcribing, while rna to prtien is a different language, that is translating
