Question

Eukaryotes have a multitude of ways of regulating gene expression. Why are all these regulatory mechanisms important to the functioning of a eukaryotic organism? 10 marls

Answer 1

Ans - These regulatory mechanisms are important to the functioning of a eukaryotic organism as-

This process in which turning on a gene is found to produce RNA and protein is known as gene expression.

For the normal and proper functioning of an individual cell synthesis of necessary proteins is required at proper place as well as time , which is done by gene expression mechanism.

This mechanism of regulation of gene expression is found to conserve energy and space .

This mechanism turns on gene only on requirement and hence it is more energy efficient.

Moreover, since only a subset of genes is expressed in each cell , therfore , space is also saved .
