BIOCHEMISTRY

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The macromolecules that serve in the storage and transmission of genetic information are:
A
carbohydrates.
B
lipids.
C
membranes.
D
nucleic acids.
E
proteins.
Explanation: 

Detailed explanation-1: -Nucleic acids are large biomolecules that play essential roles in all cells and viruses. A major function of nucleic acids involves the storage and expression of genomic information. Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins.

Detailed explanation-2: -Nucleic acids are the primary information carriers within the body. They are part of DNA and RNA and partake in protein synthesis. The genetic information stored within the nucleic acid is read by RNA during protein synthesis. Hence, this option is the correct one.

Detailed explanation-3: -In nature, just two closely related nucleic acids, DNA and RNA, function as repositories and carriers of genetic information. They therefore are the molecular embodiment of biological information.

Detailed explanation-4: -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.
