A single nucleotide addition and a single nucleotide deletion approximately 15 bases apart in the DNA cause a protein change in sequence fromPhe–Ser–Pro–Arg–Leu–Asn–Ala–Val–LystoPhe–Val–His–Ala–Leu–Met–Ala–Val–Lysa. What are the old and new mRNA nucleotide sequences? (Use the codon dictionary in Figure 9-5.)b. Which nucleotide has been added? Which has been deleted?
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.
