QUESTION 7 SR proteins bind to splicing enhancers and activate splicing by recruiting spliceosome components. Mutations that affect SR proteins will have what kind of effect on gene expression? O General transcription factors will be unable to bind to promoters. O Splicing of the mRNA will not be activated. O Ribosomes will not be able to bind to mRNA molecules in the cytoplasm. O Polyadenylation at the 3' end will be blocked. O RNA polymerase will be unable to terminate transcription.

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.
