how enzymes are involved with proofreading newly formed DNA molecules.   1. DNA polymerase does not detect damaged DNA.   2. Ligase connects the free end of the new DNA with the old DNA.   3. DNA polymerase replaces the damaged DNA with the correct nucleotide.    4. Exonuclease cuts the damaged DNA strand in order to remove the damaged section

Gene Interactions

When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.

Gene Expression

Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
