How does the sigma factor of E. coli RNA polymerase bind to promoters? Question 14 options: a region of the protein base-pairs with the DNA sequence a region of the protein binds to a stem-loop structure in the DNA a region of the protein binds to the negatively charged backbone of the DNA a region of the protein inserts into the major groove of the DNA and interacts with the bases a region of the protein inserts into the minor groove of the DNA and interacts with the bases
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.
