An RNA sequence is shown below:
AUGCCGAAACGU
Which of the following statements describes how the RNA sequence specifies the production of an amino acid chain?
A. Each individual RNA base codes for a single amino acid.
B. Each group of three RNA bases codes for a single amino acid.
C. Each group of three RNA bases codes for an enzyme that helps join amino acids together.
D. Each individual RNA base codes for the ribosome location where amino acids are assembled.
Answer (3)
B; the group of three that codes for an amino acid is called a codon.
The statement 'each group of three RNA bases codes for a single amino acid ' describes how the RNA sequence specifies the production of an amino acid chain (Option B).
What is gene transcription?
Gene transcription is the process by which a fragment of DNA called gene is used to create a messenger RNA.
Subsequently, this mRNA molecule is then used to create a protein by the process of translation .
In mRNA , the triplets of nucleotides or codons indicate the specific amino acids t hat will be added to the poly[peptide.
In conclusion, the statement 'each group of three RNA bases codes for a single amino acid ' describes how the RNA sequence specifies the production of an amino acid chain (Option B).

The RNA sequence specifies amino acids through codons, each consisting of three RNA bases. Therefore, the correct answer is option B: 'Each group of three RNA bases codes for a single amino acid.' This process occurs during translation where ribosomes convert the mRNA sequence into a chain of amino acids to form proteins.
