Of the two strands of DNA, only one will be coding. It is on it that informational RNA will be synthesized, which will then be used to synthesize the polypeptide.
Therefore, we find how many nucleotides are in one chain:
3000/2 = 1500.
The mRNA will also have 1500 nucleotides. One amino acid is encoded in three nucleotides at once, or in a triplet (codon). Let’s find the number of triplets:
1500/3 = 500.
Answer: 500 amino acids will be encrypted in this DNA.
