Respuesta :
Based on the information it can be concluded that this molecule is Deoxyribonucleic Acid (DNA).
Answer:
The correct answer will be-DNA
Explanation:
DNA is a bio-molecule which acts as the heredity material of an organism. DNA molecules exist in the helical form made of two strands.
The strands are composed of nucleotide. Each nucleotide contains four different nitrogenous bases called adenine, guanine, cytosine and thymine, a five-carbon and a phosphate group.
Since the observed molecule is double-stranded and contains different types of nitrogenous bases therefore, DNA is the material scientist was observing.
Thus, DNA is the correct answer.
