Crick et al found that not all combinations of (+) and (-) frameshift mutations results in suppression and an rII + phenotype. Which of the following is a possible explanation of why some + / - combinations do not work. Select one: a. A stop codon is located between the (+) and (-) frameshift mutations. b. A necessary part of the protein is encoded by the region of the gene located between the (+) and (-) frameshift mutations. c. Not all combinations of (+) and (-) frameshift mutations puts the ribosome back into the original reading frame. d. Two of the above explanations are correct. e. All of the first three explanations are correct.

d. Two of the above explanations are correct.

Explanation:

A frameshift mutation is commonly known as a genetic mutation that occurs as a result of the indels such as the addition or removal of certain nucleotides in the sequence of a DNA that is indivisible by three. In the presence of addition or removal, the reading frame from the initial translation to a different one. Thus, the correct option is option d.
