Question

A fragment of a strand of nucleic acid isolated from a silk moth species contains the base sequence CAGACT. The strand must be from A) DNA. B) RNA. C) a protein. D) an amino acid.

Answer 1

A) DNA

Step-by-step explanation:

T is not a nitrogen base in RNA it would be substituted for U

Answer 2

The correct answer is "A. DNA". Nucleotides are the parts or links that constitute nucleic acids and DNA is a nucleic acid that stands for Deoxyribonucleic Acid. It does not matter if the sample studied is from a silk moth or other species; the DNA strand can only be represented by the letters A, C, G, and T. In this case, the DNA sequence is represented by CAGACT.
