Question

question 4 (1 point)
gene segments may initiate, terminate, or code for a particular amino acid sequence.
a gene segment: agctag
the number of amino acids coded for by the gene segment shown above is:
1
2
3
6

Explanation:

Step1: Recall genetic - code rule

Three - nucleotide sequences (codons) code for one amino acid.

Step2: Calculate number of codons

The gene segment AGCTAG has 6 nucleotides. $\frac{6}{3}=2$ codons.

Step3: Determine number of amino - acids

Since each codon codes for one amino acid, 2 codons code for 2 amino acids.

Answer:

2
