In the yeast GAL system, the UAS is a(n) ___________________ and GAL4, the protein that binds to the UAS is a(n) ________________________. a. Repressor ; Silencer. b. Transcriptional activator ; Enhancer. c. Silencer ; Repressor. d. Insulator ; Insulator binding protein. e. Enhancer ; Transcriptional activator.
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.
