Researchers have identified a mutation in the LMNA gene, which encodes some of the pro- teins in the nuclear envelope to be associated with the development of muscular dystrophy and other auto-immune diseases. Which of the following best describes a likely direct effect of a mutation of the LMNA gene? A B It directly alters the production of ATP within the affected cells.

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.
