Answer:
Nucleic acids
Explanation:
Remember these long strands could be the ADN or the RNA, in both cases, they are formed by nucleotids, that means a complex of three parts.
A nucleotid is conformed by:
a) a nitrogenous base that in the case of DNA could be Adenine (A), Guanine (G) , citocine (C) o thymine (T). In the case of ARN are almost the same, the difference is instead of having Thymine, it will have uracile (U).
b) a phosphate group
c) a carbohydrate, in the case of ADN it will be Dexosyrribose and in the case of ARN will be ribose sugar.
