Xeroderma pigmentosuma. is a genetic disorder that results in uncontrolled cell growth.b. is a genetic disorder in which the NER system is not fully functional.c. is a genetic disorder that results in the loss of pigment in certainpatches of skin.d. results from the lack of DNA polymerase proofreading.e. Both b and d are true of this disorder.
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.
Xeroderma pigmentosum
a. is a genetic disorder that results in uncontrolled cell growth.
b. is a genetic disorder in which the NER system is not fully functional.
c. is a genetic disorder that results in the loss of pigment in certain
patches of skin.
d. results from the lack of DNA polymerase proofreading.
e. Both b and d are true of this disorder.
