Now imagine that a mutation occurred at the first G in the DNA sequence above and the G became a C. How would this affect the mRNA and the amino acid for that codon? Old DNA codon Old RNA codon Old amino acid New DNA codon New mRNA codon New amino acid T T G T T C This would be an example of which type of a point mutation?__________________________
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.
