Q: Restriction enzymes, described in Chapter 21, are enzymes that recognize
Restriction enzymes, described in Chapter 21, are enzymes that recognize a particular DNA sequence and cleave the DNA (along the DNA backbone) at that site. The restriction enzyme known as NotI recogn...

You will need to understand question 3 in More Genetic TIPS before answering this question. A gene that is normally expressed in pancreatic cells was cloned and then subjected to promoter bashing. As...
See AnswerQ: The work of McClintock showed that the presence of a transposon can
The work of McClintock showed that the presence of a transposon can create a mutable site or locus that is subject to frequent chromosome breakage. Why do you think a transposon creates a mutable site...
See AnswerQ: As described in Chapter 21, an electrophoretic mobility shift assay (
As described in Chapter 21, an electrophoretic mobility shift assay (EMSA) can be used to determine if a protein binds to a segment of DNA. When a segment of DNA is bound by a protein, its mobility wi...
See AnswerQ: Chapter 21 describes a blotting method known as Northern blotting, in
Chapter 21 describes a blotting method known as Northern blotting, in which a short segment of cloned DNA is used as a probe to detect RNA that is transcribed from a particular gene. The DNA probe, wh...
See AnswerQ: A gene, which we will call gene C, can be
A gene, which we will call gene C, can be epigenetically modified in such a way that its expression in some cells is permanently silenced. Describe how you could conduct cell-fusion experiments to det...
See AnswerQ: In the experiments described in Figure 16.8, explain the
In the experiments described in Figure 16.8, explain the relationship between coat color and DNA methylation. How is coat color related to the diet of the mother? From Figure 16.8:
See AnswerQ: 5-Azocytidine is an inhibitor of DNA methyltransferase. If this
5-Azocytidine is an inhibitor of DNA methyltransferase. If this drug were fed to female mice during pregnancy, explain how you think it would affect the coat color of offspring carrying the Avy allele...
