GENERAL KNOWLEDGE

Detailed explanation-1: -The molecules inside cells that carry genetic information and pass it from one generation to the next. Also called DNA.

Detailed explanation-2: -Because of its structure, DNA is commonly referred to as deoxyribonucleic acid. The nucleic acid has a phosphate backbone with bases such as adenine, cytosine, guanine, and thymine, while the deoxyribose portion contains pentose sugar. The-OH group at position two of the sugar ring is absent in deoxyribose.

Detailed explanation-3: -Also called deoxyribonucleic acid.

Detailed explanation-4: -As previously mentioned, DNA was first identified and called ‘nuclein’ by Swiss chemist Johann Friedrich Miescher in 1896. But its structure, the famous double helix, was not discovered until 1953 by Watson and Crick, who built upon the work of others.

Detailed explanation-5: -The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses.
