- Each molecule, or chain, of mRNA carries instructions on how to connect several "amino acids" into a peptide chain, which becomes a protein. The same way that nucleotides are building blocks for RNA, amino acids are building blocks for proteins. Evolution has produced a "genetic code" wherein each of life's 20 amino acids is coded for by a series of three nitrogenous bases in RNA nucleotides. Thus, each triplet of RNA nucleotides corresponds to one amino acid, and the sequence of nucleotides dictates the sequence of amino acids that will be linked into the peptide chain that makes a protein. While in some cases an amino acid can be represented by multiple nucleotide triplets, called codons, each codon on RNA represents only one amino acid. For this reason, the genetic code is said to be "degenerate."

∙ 10y agomRNA carries one half of the code for a protein. tRNA must match it. Both are held by a ribosome. This process will form a protein encoded from the DNA segment.

What is the function of a 5' cap in DNA transcription and translation?
The 5' cap attached to the mRNA ensures the mRNA's stability while it undergoes translation.
Matches a cell part with it function?
You can match a cell part with its function, for example the ribosomes, can be matched with "site for mRNA translation".
What is accomplished by transcription?
By the end of transcription, mRNA will be available for the next step which is translation. You require mRNA to translate into a protein for a specific function the cell needs to carry out.
What is the function of these short RNA segments during replication?
they form mrna molecules used in translation
What happens when there is a mutation in a 5' UTR of mRNA?
If there is a mutation in the 5' UTR no change in the protein function and abundance will happen.
What is the function of the cap and tail on eukaryotic mRNA?
They are involved in transporting the mRNA outside of the nucleus.
What is the function of a 5' cap in DNA transcription and translation?
The 5' cap attached to the mRNA ensures the mRNA's stability while it undergoes translation.
What would happen if a cell were unable to make mrna?
If a mutation affects the mRNA, then the sequence of amino acids that it codes for may be incorrect, causing the protein produced by the amino acids to not function properly, or it may not function at all.
What is the function of a virus' collar?
It function is to make mRNA and acts as a jet preppeled motor to help the virus move.
Which molecule is made in the nucleus but exits to function in the cytoplasm?
Messenger RNA (mRNA)
What is the function of polysomes?
many ribosomes attached to a single mRNA is called polysomes
Matches a cell part with it function?
You can match a cell part with its function, for example the ribosomes, can be matched with "site for mRNA translation".
What is the collar function in virus?
The collar function in a virus is used to create mRNA. It uses this function to move since it creates a bit of a propeller effect.
What is accomplished by transcription?
By the end of transcription, mRNA will be available for the next step which is translation. You require mRNA to translate into a protein for a specific function the cell needs to carry out.
What function does tRNA have?
It's the shuttle system for amino acids to get to the mRNA-ribosome complex.
What is the function of the ribsomes cell?
The same as the function of ribosomes in any other cell: to translate mRNA into protein that the cell can use to carry out its functions.
Which nucleic acid does not carry out its function in the ribosome?
DNA does not. RNA; mRNA, tRNA, and rRNA, all do.
