Relationship between Gene and Enzyme
Each cell of humans contains 46 chromosomes, of match 22 pairs are autosomes and the remaining pair consists of sex chromosomes. All the chromosomes of human cells have the same kind of genes. But all human cells do not have the same function. In spite of all the cells are of equal number of chromosomes, and equal number of genes, different tissues perform different functions. It is because of the variation of enzymes.
In regulating the target, engines and genes are mutually related to each other and it is definite. The activities of gene are based on enzymes. A particular enzyme performs the activities of a particular group of genes.
