BIOL 130 EXAM 4 STUDY GUIDE Chapter 16 1) A gene is made up of three exons (numbered consecutively) with two introns (intron 1 between exons 1 and 2 and intron 2 between exons 2 and 3). What would happen if there were a mutation at the 3’ splice site of intron 1? ***mRNA with all three exons along with intron 1 2) What would happen if there were a mutation in the operator of the trp operon? ***the trp operon would continuously express the genes 3) In eukaryotes, where would a prote...

Question 1 of 10 1.0/ 1.0 Points After many years of difficult research, your company invented a drug that increases the enzyme rate for the synthesis of an important metabolite. Patients with mutations in the enzyme lack the metabolite and have devastating symptoms. Your team is thrilled to have a drug that speeds up the enzymatic rate. At your celebration, the new intern pipes up: “You guys didn’t have to do all that work after all! Instead of giving patients this new drug, you coul...

BIOL 133 Week 15 Chapter 19 What is the only way to introduce a new allele into a species? In South America, there is a specific type of frog where the male uses a loud call in order to attract females, even though this makes him more likely to be found by a predator. This is an example of The accumulation of mutations in a population over generations leads to If alleles that cause disease are constantly being selected against, why would there be any disease-causing alleles in a population...
