- 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."
The purpose of messenger RNA (mRNA) is to be the transcript of the DNA sequence, and the template for protein synthesis by the ribosome during translation.
mRNA 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.
mRNA serves as a template to encode for proteins. They tell ribosomes the precise sequence of amino acids needed to make a particular protein.

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.
MRNA is translated into?
mRNA is translated into proteins by the ribosomes in the cell. This process involves decoding the mRNA sequence into a specific amino acid sequence which ultimately determines the protein's structure and function within the cell.
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".
When transcription is complete where does LUC mRNA move to?
After transcription is complete, the mRNA transcript moves out of the nucleus into the cytoplasm, where it can be translated into protein. If the mRNA codes for the LUC gene, the protein product (luciferase) can then perform its function within the cell.
What is the function of these short RNA segments during replication?
they form mrna molecules used in translation
What is the function of the cap and tail on eukaryotic mRNA?
The cap and tail on eukaryotic mRNA play important roles in mRNA stability and translation. The 5' cap protects the mRNA from degradation and helps in the initiation of translation. The poly(A) tail at the 3' end of mRNA also plays a role in mRNA stability and regulation of translation.
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.
Which nucleic acid does not carry out its function in the ribosome?
DNA does not carry out its function in the ribosome. DNA's main function is to store genetic information, which is then transcribed into messenger RNA (mRNA) to be translated in the ribosome to produce proteins.
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.
MRNA is translated into?
mRNA is translated into proteins by the ribosomes in the cell. This process involves decoding the mRNA sequence into a specific amino acid sequence which ultimately determines the protein's structure and function within the cell.
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".
Which is the longest mRNA?
The longest mRNA in humans is thought to be the mRNA for titin, a protein found in muscle cells. Titin mRNA has over 100,000 nucleotides and is responsible for producing the enormous titin protein that helps muscles function properly.
What function does tRNA have?
It's the shuttle system for amino acids to get to the mRNA-ribosome complex.
When transcription is complete where does LUC mRNA move to?
After transcription is complete, the mRNA transcript moves out of the nucleus into the cytoplasm, where it can be translated into protein. If the mRNA codes for the LUC gene, the protein product (luciferase) can then perform its function within the cell.
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.
How does DNA contribute to its function?
By trascription mRNA is produce . This RNS on reching the cytoplasm functions accordingly.
Which molecule is made in the nucleus but exits to function in the cytoplasm?
mRNA (messenger RNA) is the molecule that is made in the nucleus during transcription, carrying the genetic information from DNA, and then exits to function in the cytoplasm during translation to direct protein synthesis.
