When the DNA of a human cell becomes damaged, the p53 geneis activated. What is the general function of the p53 protein?Is it an enzyme, transcription factor, cell-cycle protein, orsomething else? Describe three ways in which the synthesisof the p53 protein affects cellular function. Why is it beneficialfor these three things to happen when a cell’s DNA hasbeen damaged?
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.
