NEET BIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -What carries the genetic information? Genetic information is all of the information stored in our DNA. DNA stands for “deoxyribonucleic acid.” The strands of DNA look like a twisted ladder, known as a double helix.

Detailed explanation-3: -Your chromosomes contain the blueprint for your body – your genes. Almost every cell in the human body contains a copy of this blueprint, mostly stored inside a special sac within the cell called the nucleus. Chromosomes are long strands of a chemical substance called deoxyribonucleic acid (DNA).

Detailed explanation-4: -Thus, within the same molecule, nucleic acids encode genetic information, the genotype (i.e., the sequence of nucleobases), as well as the phenotype (the three-dimensional fold or function) and thus can be evolved directly at the molecular level.
