If DNA is the superintedent and mRNA is the order to the assembly line (riboso) what might be the role of tRNA
913242
tRNA is for transcription.  During transcription tRNA delivers the correct amino acid to the groing polypeptide chain.  The tRNA reads the sequences in pairs of 3 called codons.  Each codon codes for an amino acid, some codons code  for the same amino acid.  During transcription the mRNA binds to the rRNA and tRNA (transription) binds and starts at the AUG start codon.

mRNA is the RNA that carries information during transcription and translation. It has codons, which match up with the anticodons on tRNA. tRNA is the RNA that bonds to amino acids and transfers them to ribosomes, and mRNA. The reason RNA is used is because the cytoplasm is too damaging to DNA, so RNA is kind of a scapegoat. Hopefully, this helps.

All contain carbon, oxygen, hydrogen and nitrogen.\nAmino acids form proteins, while DNA and RNA are formed from nucleic acids.\nDNA stores the genetic code, mRNA transfers portions of that code to the cytoplasm, and is the transcript from which amino acids are strung together, in a specific pattern, to form the new peptide or protein.

If a cell has a sequence of DNA that can be transcribed, that means it can be made into RNA. RNA is then translated into proteins for the cell to use. Every 3 RNA nucleotides codes for an amino acid which are used to build proteins. The proteins are built in the cell's ribosomes using messenger RNA and transfer RNA; both of which were transcribed from the original DNA sequence.\n\nSo the cell that has a sequence of DNA that can be transcribed has the ability to make protein structures for whatever it needs; enzymes or physical structure.

The primary function of DNA is for protein synthesis.  Within the DNA sequence are millions of templates for proteins.  A protein called RNA polymerase "reads" the DNA sequence and makes a strand of mRNA (Ribonucleic Acid).  This strand of mRNA, which is similar to a negative image of a photograph, gets transfered to the ribosomes surrounding the nucleus.  In the ribosomes, molecules of tRNA bond with the matching triplets of mRNA.  Each molecule of tRNA is bound to an amino acid.  As more and more molecules of tRNA bond to the mRNA, the amino acids in tow are bonded together in sequence.  Eventually, the result is a fully functional protein.

mRNA is a carrier  of a genetic message hence the name. It carries the message in the form that a machinary for protein synthesis will understand and translate in amino acid sequence. Ribosomes and tRNAs can not directly read the genetic information from DNA hence the need for the mediator to do the job.

No. The central dogma, means just that. DNA to RNA to protein. Amino acids must be assembled on the ribosomal workbench by the interaction of, mRNA and tRNA, which followed from DNA's instructions.

RNA is the one also found in the cytoplasm.

hiya, if you mean how does it happen here goes:\nDNA from the nucleus is transcribed to form messenger RNA (mRNA) which then carries the information from the DNA out of the nucleus to the ribosomes which are attached to the endoplasmic reticulum its here that the proteins are synthesised. Not all of the DNA actually codes for proteins and the code that is carried on the mRNA contains special sequences that control the start and stop of the protein synthesis these are called start and stop codons, a codon just being a set of 3 bases which code for something, in the case of proteins a specific amino acid. The ribsome will then read the series of codons that is between the start codon (AUG) and the stop codon (UAG, UUA etc) each codon has a corresponding tranfer RNA (tRNA) which brings in a specific amino acid. As the tRNA interacts with the mRNA the amino acids join with peptide bonds to form the long chain protein, this continues until the entire frame of the mRNA sequence is read and the protein is fully synthesised.\nHope this more or less answers your question :>

rna is copy of the dna used in transcription (i think) then it's translated back into dna somewhere else in the cell
589633
1)there are 5 to 9 nucleotides on 5' mRNA named Shine Delgarno which are the match for 16SrRNA on 3' in the small subunit of ribosome.so 16SRNA conduct ribosome to AUG by binding to shine....and helps to initiate the protein synthesis.\n\n2)there are special sites on 16SrRNA which have a direct reaction with antisense on tRNA\n\n3)it binds to IF3(initiation factor3)

when dna is copied to rna this is called translation, when rna makes the protien it it is called transcription

Each amino acid is coded for by a 3-nucleotide codon.  So the mRNA would need at least 450 nucleotides.\n\nBut real mRNA often has extra nucleotides at the beginning or the end that aren't translated into protein.  Sometimes, they are functional (for instance, Iron-Response elements, or IREs tie the translation of that mRNA to iron levels in the cell), sometimes, they aren't.  \n\nLikewise, with DNA you would need at least 450 DNA base pairs, but realistically, there are promotors, or other DNA sequences that don't code for protein, but control when the mRNA is or isn't made, depending on the situation.  Most eukaryotes also have introns, as sometimes, different splice variants are called for in different situations.

(m)\n\ntRNA - short-chain RNA molecules present in the cell (in at least 20 varieties, each variety capable of combining with a specific amino acid) that attach the correct amino acid to the protein chain that is being synthesized at the ribosome of the cell (according to directions coded in the mRNA)

DNA->RNA->Polypeptide->Protein

Cells make a DNA template from RNA (similar to DNA, but with a different sugar and one different nucleotide, and almost always single-stranded) called mRNA (messenger RNA).  This goes to a part of teh cytoplasm where a protein-builing machine called a ribosome matched every three nucleotides of the RNA with a distinct sort of molecule (tRNA, for Transfer) matches every three-nucleotide sequence with any of twenty different amino acids.  This process works to make a chain of amino acids, and this chain becomes a protein.  (there are a few exceptions to all of this, and some complicated additional steps, but that's generally the basis of how a protein comes about).  The chain of amino acids will fold into a certain, thermodynamically favorable conformation, and that shape will generally dictate its function.  Sometimes, more than one chain will work together to form a proteins.\n\nProteins do everything in the body.  Some are structural (like ropes or girders or bungee cords), some are like motors (like pumps, or like train cars that walk along tracks carrying material, or like growing fibers that push the cell membrane), some will act as messages to other cells, or to the cell nucleus to start building new proteins in response to a change in environment; some work to turn fats and sugars into an energy source (eg ATP), and some will sit in the membrane holding out long carbohydrate chains to help other cells recognize one cell from another.
