Question

In evolution the studies can be made at molecular level. For example, the proteins present in the blood of man and ape are similar. The base sequence in nucleic acids and amino acids sequence in proteins of related organisms is alike. These are the examples which are specially referred to in
a. Convergent evolution
b. Molecular analogy
c. Molecular homology
d. Homoplastic appearance

Answer 1

Hint: First, we've to grasp concerning key conception to know the question. Those organs that have identical basic structure and biological process origin are referred to as homologous organs. The organisms that possess such organs are aforesaid to possess originated from common ascendentes.

Complete answer:
The base sequence in nucleic acids and organic compound sequence in proteins in connected organisms are alike. This is often thanks to molecular similarity between connected species. All living beings essentially have the same chemical composition of desoxyribonucleic acid, aside from variations within the sequence of chemical element bases.

The degree of similarity between the deoxyribonucleic acids of 2 species is calculated by the pairing property of DNA strands. they're directly proportional to every alternative, the bigger the degree of pairing within the strands of 2 species, the nearer are similarities within the genetic message contained within the DNAs of 2 species. Human and Pan troglodytes have 100% degree of pairing.

Consider, as an example, the seal’s flipper, the cat’s paw and also the human hand. In plants, a thorn of vine differs from a plant part of magnoliopsida genus in its operation, each are set in an exceedingly similar (axillary) position and have similar origin.

The genetic codons are universal altogether organisms this implies the common ancestry of all organisms. whereas the presence of native Australian people blood grouping in humans and apes recommend their common ancestry. Each of the higher than examples are proof of Evolution from biological science and organic chemistry showing similarity in ancestors and current evolved species.

Hence, the correct answer is option (C).

Note: Homologous organs shoe divergent evolution and radiation. It's the event of dissimilar useful structures in closely connected clusters of organisms. The presence of ABO blood type grouping in humans and apes indicates their similar ancestors.
