correct answers in bold<\/strong><\/p>\n

#1 (5 points)<\/strong> How can the abundance and function of a gene\u2019s products (RNA, protein) be regulated inside the cell?<\/p>\n

D. All of the above<\/strong><\/p>\n

#2 (5 points)<\/strong> You have a lacI<\/span>S<\/sup> (\u2018super repressor\u2019) mutant of <\/span> coli<\/em>. The LacI protein of this mutant cannot bind lactose, but can bind the operator. The lac operon structural genes (lacZ, lacY, lacA) will be expressed:<\/span><\/p>\n

A. Only<\/u> when there is<\/u> lactose in the growth media.<\/p>\n

B. Only<\/u> when there is not<\/u> lactose in the growth media<\/p>\n

C. Always<\/u>, regardless of whether or not there is lactose in the growth media<\/p>\n

#3 (5 points)<\/strong> You are a population geneticist studying a diploid species of salamander. The gene B influences salamander coloration. Two alleles of this gene exist, allele B<\/em> (dominant) results in yellow salamanders, allele b<\/em> (recessive) results in brown salamanders. The frequency of allele B<\/em><\/u> is 0.07. What is the frequency of the b<\/em> allele?<\/p>\n

A. 0.93<\/strong><\/p>\n

B. 0.14<\/p>\n

C. 0.07<\/p>\n

D. 0.01<\/p>\n
