Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Nucleic acids are one of the four major macromolecules. The main function of nucleic acids is to-
A
aid in development, the immune system, and blood clotting.
B
absorb energy from the Sun and transport it around the cell.
C
carry genetic material that helps to create structures inside the cell.
D
act as enzymes, cell signals, and structural support for the cell.
Explanation: 

Detailed explanation-1: -It is found in all cells and also in some viruses. Nucleic acids have a very diverse set of functions, such as cell creation, the storage and processing of genetic information, protein building, and the generation of energy cells.

Detailed explanation-2: -Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.

Detailed explanation-3: -Among other important roles, nucleotides can serve as sources of energy in the form of ATP, physiological signaling mediators, secondary messengers, and allosteric enzyme effectors.

Detailed explanation-4: -Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in living organisms, all the way from single-celled bacteria to multicellular mammals like you and me.
