A researcher identifies a strand of genetic material that has the sequence ACCGTA. What is the substance, and how will it be identified?

A. DNA, because it contains the bases A, T, G and C
B. DNA, because it contains the sequece GTA
C. RNA, because it contains the bases A, T, T and C
D. RNA, because it contains the bases A, U, G and C

This nucleic acid is DNA, because it contains the bases A, T, G and C (Option A).

Deoxyribonucleic acid (DNA) is a double helix molecule consisting of two strands of nucleotides.In DNA, there are four types of nucleotides, each having one different nitrogenous base: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T).During transcription, a sequence of DNA (e.g., a gene) is used as template to create an RNA sequence, usually an mRNA sequence that is then used to create a protein by a process called translation.In RNA, Thymine bases are replaced by Uracil (U) bases.

In conclusion, this nucleic acid is DNA, because it contains the bases A, T, G and C (Option A).
