Which of the following statements about the nucleolus is not true? a. The nucleolus is a membrane-bound structure. b. rRNA genes are transcribed in the nucleolus. c. Ribosomal subunits are synthesized in the nucleolus. d. rRNA molecules are chemically modified in the nucleolus.
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.
