Rebekah is studying a molecule and trying to determine if it is dna or rna. which kind of molecule is she studying?

a-carbohydrate
b-protein
c-nucleic acid
d-lipid

Ans. (C).nucleic acid.

Nucleic acids are complex organic biomolecules, which are found in all living organisms. They are made up of nucleotides and are of two types, DNA and RNA.

The DNA molecules are made up of deoxyribose sugar (which lacks 2'-OH group), phosphate molecule, and nitrogen bases (cytosine, thymine, guanine, and adenine). On the other hand, RNA molecules are made up of ribose sugar (having 2'-OH group), phosphate molecule, and nitrogen bases (cytosine, uracil, guanine, and adenine).

So, Rebekah is studying the nucleic acid molecule that can be either DNA or RNA.

Thus, the correct answer is option (C).

the answer is b.) hydrogen bonds between bases.
