radioactively labeled cDNA is used to probe RNA isolated from kidney by Northern blotting. Two bands are seen on the blot. Which of the following reasons is least possible? A. A single pre mRNA is spliced into two different messages B. There are two promoters for the gene C. There are two related genes expressed in kidney D. The mRNA is cleaved in the cytoplasm as part of its degradation Explain why the answer is B or E E. There is a single mRNA produced but some is not polyadenylated
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.
