Research has demonstrated that the composition of a gene’s promoter can affect alternative splicing of its RNA transcript. For example, promoters that are activated by certain transcriptional activator proteins cause one form of alternative splicing; when these activators are not present, a different form of splicing takes place. Propose some possible mechanisms by which the promoter could affect alternative splicing.
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.
