Given the following figure, what would be the effect of a mutation that occurred in the insulator that prevented the binding of the insulator-binding protein?

Suppose a scientist discovered a mutant strain of C. elegans worms that had lost the ability to regulate gene expression via RNA interference mechanisms. Which of the following might she predict is a possible source of this defect?

If the bottom strand of the DNA is the template, the tRNA anticodon sequence for the first RNA codon, left to right or 5 to 3, is:

Which of the following statements about regulation of gene expression is CORRECT?

Translation in prokaryotes and eukaryotes has some similarities but differs in important ways. Which of the following statements about similarities and differences in prokaryotic and eukaryotic translation are TRUE? (Select all that apply.)

Transposable elements are found:

An insertion of two nucleotides in the protein coding region of  a gene will cause a frameshift.

A geneticist is studying a mutation in a population of turtles that causes their shells to become extremely brittle. She determines the mutation is caused by the loss of two nucleotides in the coding region of a gene. Upon studying the mutant protein that is produced, she observes that it is 312 amino acids in length, as compared to the normal protein that is 588 amino acids in length. This mutant protein can no longer carry out its normal function of assisting in the stiffening of a turtle’s shell. Which of the following could NOT describe this mutation?

Which of the following types of eukaryotic gene regulation take place at the level of DNA?
