Tyrosine is listed as a non-essential amino acid because it can be synthesised from the essential amino acid phenylalanine.
<u>Explanation:</u>
Amino acids are classified as essential and non essential according to whether they can be synthesized in the body itself or should be supplied by the diet. Essential amino acids cannot be synthesized in the body of the organism and thus can be obtained only from the diet. In the case of human beings, valine, phenylalanine, methionine etc are examples of essential amino acids.
Non essential amino acids can be synthesized within the body of the organism. Thus they need not be supplied by the diet. Alanine, aspartic acid etc are some of the non essential amino acids in human beings. It is given here that animals cannot synthesize tyrosine from shikimate-3p due to the lack of EPSP synthase.
But the amino acid tyrosine can be synthesized from the amino acid phenylalanine which is an essential amino acid. Thus tyrosine will be a non-essential amino acid.
According to the research, the correct option is differentiation. The expression of different subsets of genes to manufacture proteins drives the specialization of distinctive cell types and is referred to as differentiation.
<h3>What is
differentiation?</h3>
It is the process by which a cell becomes another more specialized cell type that will involve morphological variations in the composition of its membrane and are produced due to a reprogramming of its gene expression.
Evolutionarily it has remained a stable process, occurring as the morphological and physiological transformation of meristematic cells into adult tissues or specialization.
Therefore, we can conclude that according to the research, the correct option is differentiation. The expression of different subsets of genes to manufacture proteins drives the specialization of distinctive cell types and is referred to as differentiation.
