When DNA polymerase is replicating chromosomes, it often encounters regions with repetitive DNA, organized in repeat motifs. DNApol will replicate these regions, but often extra repeat motifs will be inserted, or deleted. This is a result of A.slipped mispairing, in which DNApol interacts with histone modifiers to replicate a segment twice. B. Caf-1 becoming involved with the replisome, displacing DNApol from the template strand. C. segments of DNA being methylated, preventing DNApol from recognizing that they must be synthesized. D. slipped mispairing, in which either the template strand or the newly synthesized strand form a hairpin loop, causing DNApol to replicate a segment twice.

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.
