Nitrous acid is a mutagen. It can react chemically with cytosine to change it to uracil in a DNA strand. Using your knowledge of DNA that undergoes transcription, explain the effect of this mutagen on a strand of DNA structurally and what the implications are for transcription of the mRNA strand and protein.
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.
