Which of the following is NOT true of miRNAs? A. Pri-miRNAs are processed by Drosha in the nucleus to form pre-miRNAs which are cleaved by dicer in the cytoplasm to generate a miRNA. B. miRNAs always lead to the degradation of their mRNA targets. C. miRNAs can be encoded within the vertebrate genome within introns and within intergenic regions. D. miRNAs can generally target more than one mRNA
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.
