Question

Select all that apply: Nucleic acids _____.

are the largest of the four main biological macromolecules:
determine whether an organism is a bacterium, tree, mouse, or human:
are the building blocks of proteins:
consist of DNA and RNA

Answer 1

I would believe the correct responses would be option 1,2,4.

Answer 2

The correct answer will be: are the largest of the four main biological macromolecules, consist of DNA and RNA and whether an organism is a bacterium, tree, mouse, or human.

Step-by-step explanation:

Nucleic acids are the macromolecules which act as genetic material of organisms.Two types of nucleic acids-DNA and RNA act as genetic material.

The structure of these nucleic acids are long chains formed by the bonding of nucleotide units. These nucleotides are made up of 5-C sugar, phosphate and nitrogenous base which make up the long chains of molecule and forms one of the largest biological macromolecule.

The order of nitrogenous bases (adenine,guanine, cytosine, thymine) in the functional part of DNA also called genes decides the fate of cell as they code for proteins. The sequence of these bases in genes is highly conserved among organisms giving uniqueness to the organism but the variation in the sequence of DNA or nitrogenous bases leads to the formation of new organism or new species.

Thus, these options are the correct answer.
