where in the cell does transcription takem place? what about translation?

To be more precise, ribosome is in the cytoplasm which is outside the nucleus.

The answer is D.  Protein synthesis takes place along the endoplasmic reticulum.  The synthesized proteins move to the golgi apparatus, and are then packaged in vesicles to be transported out of the cell (those that are destined to leave the cell).  In your example, the radiolabeled proteins are destined to leave the cell, so they would need to go to the cell membrane in order to exit the cell.  Going to the nucleus would be going the wrong direction.\n\nhttp://users.rcn.com/jkimball.ma.ultranet/BiologyPages/G/Golgi.html

It's actually very simple.  Just know what the letters before "RNA" code for.  tRNA (transfer RNA) transfers correct amino acids to a growing polypeptide chain.  snRNA (small nucleolar RNA) guide chemical modifications of rRnA's.  mRNA (messenger RNA), as the name implies, encodes and "carries" information from DNA during transcription to whatever sites are undergoing protein synthesis. rRNA basically makes the proteins.  Sorry, that's the shortest I could make it.  It's a rather difficult topic.

Transcription 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.

Yes.  DNA is transcribed into RNA, and RNA is translated into proteins.  \n\nI always kept that straight by thinking of transcription as like taking notes when someone is talking (same language) and translation as translating those notes into another language.  Going from DNA to RNA you're going to use the same building blocks (bases - purines and pyrimidines)or the same "language", but going from RNA to proteins requires going from one building block to another (bases to amino acids), or a different language.

mRNA is the RNA that is transcribed from the DNA in the nucleus and is used as the template for translation.\ntRNA is the RNA that holds the polypeptide and is used in translation to connect the polypeptides in the correct order to make a protein.\nrRNA is the RNA that is in a ribosome. The different subunits of the ribosome are used like an assembly line for the mRNA and the tRNA to connect the polypeptides.

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.

Proteins are made in the cytoplasm of cells, outside of the nucleus.  So whenever the nucleus needs to use a protein (like polymerase, transcription factors, gyrases, etc.) those proteins need to be brought in from the cytoplasm.  The process by which this happens is called nuclear import.

Increasing evidence suggests nonrandom localization of DNA sequences in the cell nucleus. Changes in intranuclear gene location as a function of transcriptional activity has been established in several experimental systems

Yup, Ribosomes. Ribosome is an organelle in cells that assembles proteins. Ribosomes are composed of ribosomal RNA and ribosomal proteins . It translates messenger RNA (mRNA) into a polypeptide chain It can be thought of as a factory that builds a protein from a set of genetic instructions. Ribosomes can float freely in the cytoplasm  or bind to the endoplasmic reticulum, or to the nuclear envelope.

RNA polymerase is necessary for making RNA from DNA and is found in pretty much all organs, cells, and viruses.\n\ndoes this help?

All mRNA signals are translated by ribosomes, usually on rough endoplasmic reticulum. Cytoplasmic proteins will then be released to the cytoplasm, secreated proteins will be packaged up into vesicles by the golgi apparatus, and membrane proteins will be moved to the membrane.\nHope this helps :)

The cellular and genetic process of transcription produces complementary messengerRNA(mRNA) strands from the gene DNA thus providing a template on which proteins can be synthesised (during translation). \n\nIt involves the combined activity of several enzymes (notably RNA polymerase) and is followed by a process called splicing which removes the non coding (and so called junk) parts of the genetic code.

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.

Think of it this way... when you "transcribe" something you are WRITING it down... this is what happens during transcription... a copy of the complimentary strand of DNA is made in the mRNA (messenger) basically, a MESSAGE is taken down so that it can be delivered to the ribosomes where it will be "translated" into proteins... \n\nTranslation is when that message is actually "translated" into a string of proteins from the original message, like following a recipe to make a cake (the cake is the string of proteins that section of DNA holds the recipe for and the recipe is the message encoded into the mRNA).

Transcription is when the nucleus of a cell wants to send a "message" for a protein (polypeptide chain) to be made. It copies this "message" from part of the DNA onto an m(essenger)RNA strand, in which the Thymine of the DNA is now the Uracil of the RNA.\n\nex) DNA message: TAC CGG TAA\n           mRNA: AUG GCC AUU\n\nAfter that is translation, where the message from mRNA gets read by the ribosome to build a polypeptide chain that will eventually become a protein!

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.
