The Muts proten slides along the DNA and finds a mismatch. The MutS/Mutl complex binds to MutH, which is alroady bound to a hamimethylated sequence. ČTAG Parontal - strand - MutH Mutl -Muts MutH makes a cut In the nonmethylated strand. Mutu (not shown) separates the DNA strands at the cloavago site, and an exonuclease (not shown) digests the nonmethylated strand until It passes the site where MutS is bound, removing the Incorract base. Incorrect base GA MutH cleavage site DNA polymerase fills in the vacant reglon. DNA ligase seals the end Themismatch has been repáred correctly.

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.
