You are working in a lab studying Progeria. You design an expression vector containing a mutated form of the lamin gene that codes for a lamin protein that can no longer be phosphorylated. What do you predict would happen if you express this mutant form of lamin in a cell line? Lamin proteins would not be transported into the nucleus and would remain in the cytosol. Nuclear lamins will be unable to produce dimers, as the coiled-coil formation will be disrupted. Disassembly of the nuclear lamins will occur prematurely. Nuclear lamins will no longer disassemble properly during prometaphase. O Nuclear lamins will no longer assemble properly during telophase. O O O O

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.
