Question

the dna sequence atcagcgctggc is part of a gene. how many amino acids are coded for by this message? 2 12 20 4

Explanation:

Step1: Count the number of nucleotides

The DNA sequence is ATCAGCGCTGGC. Counting each letter (nucleotide), there are 12 nucleotides.

Step2: Divide by 3 (since 3 nucleotides = 1 codon = 1 amino acid)

Number of amino acids = $\frac{12}{3}=4$

Answer:

4
