The correct answer is A
The scientist can determine that this nucleic acid is a DNA molecule, because it contains Thymine, which does not occure in the RNA molecule. The RNA molecule contains Adenine, Guanine and Cytosine just like the DNA, but unlike the DNA it contains Uracil, not Thymine.
Secondly, the scientist can say with certainty that this DNA molecule is surrounded by a nucleus based on the structure of the nucleic acid described. Only eukaryotic cells have ladder structure. The prokaryotic cells have circular DNA and do not have any organelles, like the nucleus. Therefore, from the ladder structure of the DNA the scientist can see that the cell has a nucleus.
The amino are essential to build the DNA
