Silent Mutations in DNA – Notice one nucleotide pair differs from the normal sequence given in question #6. 5’ ATG GGA GAT TAT TAG 3’ (non-template strand) 3’ TAC CCT CTA ATA ATC 5’ (template strand) What would be the mRNA sequence when this mutated DNA is transcribed? What would be the resulting amino acid sequence when your answer to 7a is translated?
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.
