A scientist studies the production of a key digestive enzyme in silk moths. The moths have one gene for this enzyme, and the scientist extracts mRNA transcribed from this gene as well as protein translated from it. The gene has three introns in its sequence. If the researcher compares mRNA from inside the nucleus to mRNA from the ribosomes, what will be found? A. less mRNA in the nucleus B. shorter mRNA in the ribosomes C. identical mRNAs in both places D. mRNA covalently attached to protein in the nucleus
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.
