1. a sequence of sugars, phosphates, and nitrogenous organic bases

2. a complex molecule containing the genetic code

3. a nucleic acid that participates in the synthesis of proteins

DNA
nucleic acid
RNA

Answer :

Answer is Nucleic Acid

Reasoning - Because phosphate, sugar, nitrogenous make up the Acid !!! lol RNA is synthesis of protein. DNA is the control of genetics which is obvious.

Answer:

1: Nucleic acid;   2: DNA ;   3: RNA

Explanation:

Nucleic acid is a sequence of sugars, phosphates, and nitrogenous organic bases. Examples of nucleic acid are DNA and RNA. DNA is a complex molecule containing the genetic code. Transcription of DNA forms mRNA which in turn serve as template for protein synthesis. RNA is a nucleic acid that participates in the synthesis of proteins.
