A gene has 3 exons and 2 introns. While analyzing a mutant, you discover that 9 basepairs are inserted in the middle of intron 1 of this gene. What is the effect of this insertion on the protein? Select one: a. this insertion will have no effect on the protein b. The protein is likely non-functional because the insertion caused a frameshift c. The protein has 3 extra amino acids d. the transcription will be terminated e. the type of...

1) Suppose that gene A 3,000 bp. Suppose that g contained within intron 1 opposite directions for the two genes. covers 10,000 base pairs (bp) and has 2 exons; the intron in gene A is ene B covers 1,500 bp and has two exons. Gene B is completely of gene A. The direction of the transcriptional bubble moves in A. Draw the genomic organization (i.e., exons and introns) of gene A AND gene B. Label the polarity of the DNA...

A gene has 3 exons and 2 introns. While analyzing a mutant, you discover that 9 basepairs are inserted in the middle of intron 1 of this gene. What is the effect of this insertion on the protein? Select one: a. the type of amino acid replacement will determine the effect of this insertion O b. The protein is likely non-functional because the insertion caused a frameshift c. The protein has 3 extra amino acids d. this insertion will have...

a) Its time to refresh your memory on the different types of DNA mutations. Define the following: • point mutation, substitution, transversion, transition, point deletion, point insertion, frameshift mutation b) Define “gene regulation” and describe why this is an important process for all cells? c) Define operon and describe the major components that exist in an operon. Why are operons most common in prokaryotes but not in eukaryotes? d) Differentiate between “inducible operon” and “repressible operon”.
