Which of the following statements concerning p53 is NOT correct? O a. O b. O C. p53-dependent transcription of target genes leads to cell cycle arrest or cell death (apoptosis). Loss of p53 function results in loss of checkpoint controls. Loss of p53 function creates an environment that is permissive for genome instability--that is, more damaged cells with chromosome aberrations and mutations survive and propagate. O d. p53 is a tumor suppressor protein which is largely responsible for protecting cells from cancer- causing DNA-damaging agents.
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.
