NEET BIOLOGY

Detailed explanation-1: -Thus, based on the above information we can conclude that the metabolism, translation, splicing life processes evolved around RNA. Hence, the correct answer is option (D).

Detailed explanation-2: -tRNA charging: The process of attaching an amino acid to its respective transfer RNA (tRNA) is known as amino acid activation, also known as aminoacylation or tRNA charging.

Detailed explanation-3: -The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction. In humans, who represent the most complex form of life, there are additional requirements such as growth, differentiation, respiration, digestion, and excretion.

Detailed explanation-4: -RNA serves as a messenger for the transmission of information. RNA carries genetic information as well, thus functioning as genetic material. The genome of certain viruses is made up of RNA.

Detailed explanation-5: -The first proof about RNA being the hereditary material and also capable of transmitting genetic data comes from experiments with TMV or tobacco mosaic virus. The experiments were done by Fraenkel Conrat. TMV is a small virus that exists as a single molecule of RNA enclosed in a capsule of cylindrical protein coat.
