QUESTION 17 You have engineered a new mutation that removes the UAS sequence upstream of the GAL7 gene. How will this mutation affect GAL7 expression? Use the options below to type in the appropriate letter only here: A. GAL7 will not be expressed in the absence of galactose, but it will be expressed in the presence of galactose B. GAL7 will be expressed in the absence or presence of galactose C. GAL7 will be expressed in the absence of galactose, but it will not be expressed in the presence of galactose D. GAL7 will not be expressed in the absence or presence of galactose E. there is too little information to determine whether GAL7 will be expressed Will this mutant allele's effect on GAL7 expression be dominant or recessive to the wild-type allele in a diploid yeast cell? Use the options below to type in the appropriate letter only here: A. recessive B. dominant C. too little information to determine QUESTION 18 In eukaryotes, the ribosome is positioned to begin translation by: O A. nucleotide complementarity between the 165 FRNA and the Shine-Dalgarno sequence located upstream of the correct translational initiation codon. O B. scanning the MRNA from the 5' end for the first AUG codon. OC. specific recognition of the AUG initiation codon by the large ribosomal subunit. O D. unique interactions between the formyl-methionine charged tRNA and the initiation codon. O E. base-pair complementarity between the AUG initiation codon and the 3'-UAC-5' anticodon in the initiator tRNA.

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.
