Yeast chromosome XII contains the HAP1 gene that contains codes to regulate proteins involved with cellular division. The SCM4 gene, on chromosome VII, produces membrane proteins and has a binding site for HAP1 in its promoter region. The diagram shows the location of the binding site for HAP1. Which of the following claims could scientists make regarding the interaction between HAP1 and SCM4? A - HAP1 would prevent translation of all SCM4 proteins by blocking the binding sections of messenger RNA and amino acids. B - HAP1 would decrease the translation of SCM4 proteins because promoter sections first bind transfer RNA and amino acids. C - HAP1 would stimulate transcription factors such as RNA polymerase and prevent all SCM4 proteins from beginning transcription. D - HAP1 would increase the transcription of SCM4 proteins because promoter sections bind RNA polymerase and initiate transcription.
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.
