Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True or False:Nucleic acids function primarily to carry genetic instructions and direct cellular activities.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Nucleic acids are key macromolecules in the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

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: -Nucleic acids are molecules comprised of nucleotides that direct cellular activities such as cell division and protein synthesis. Pentose sugar, a nitrogenous base, and a phosphate group comprise each nucleotide.

Detailed explanation-4: -Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder-a shape known as a double helix.
