Step 1
Ans:
Amino acid:
The organic molecules which has amino terminal and carboxy terminal ends and is the building block of protein is referred to amino acid.
Step 2
Ans:
Q1:
Based on the amino acid sequence the Chimpanzee and gorilla are most closely related to human since their amino acid sequences matches exactly. However, the organisms such as Rhesus monkey, horse and kangaroo are distant than humans, since their amino acid sequences are not exactly matching.
Q2:
The genes as well as DNA are the main evolutionary forces. The changes in the DNA and genes leads to changes in phenotype and that's how organisms adapt or evolve in diverse environment. Hence study of genes and DNA is crucial in studying evolution.
