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.
1. If deoxyribonucleotides that lack the 3’-OH groups are added during the replication process, what do you expect will occur?
2. Why is it more likely that insertions or deletions will be more detrimental to a cell than point mutations?
3. Describe what happens when a nonsense mutation is introduced into the gene encoding transposase within a transposon.
