For the following structural characteristics, decide if it is a characteristics dna, a characteristic of rna, a characteristics of both dna and rna, or a charactetristic of both dna and rna, or a characteristic of neither dna nor rna. it contains thymine as a base.

The correct answer would be "it is a characteristics DNA".

Thymine is one of the four nitrogenous bases present in the DNA. The other three nitrogenous bases are adenine, guanine, and cytosine. It base-pairs with adenine in the double strand structure of the DNA.

In contrast, In RNA is usually a single strand structure in which uracil is present in place of thymine.
