Q: Gene mutagenesis is also used to explore the structure and function of
Gene mutagenesis is also used to explore the structure and function of proteins. For example, changes can be made to the coding sequence of a gene to determine how alterations in the amino acid sequen...
See AnswerQ: Northern blotting depends on the phenomenon of the binding of a probe
Northern blotting depends on the phenomenon of the binding of a probe to mRNA. In this technique, explain why binding occurs.
See AnswerQ: In Northern and Western blotting, what is the purpose of gel
In Northern and Western blotting, what is the purpose of gel electrophoresis?
See AnswerQ: Bacillus thuringiensis makes toxins that kill insects. These toxins must be
Bacillus thuringiensis makes toxins that kill insects. These toxins must be applied several times during the growth season to prevent insect damage. As an alternative to repeated applications, one str...

Explain why a heteroduplex region may be produced after branch migration occurs.
See AnswerQ: What is the purpose of a Northern blotting experiment? What types
What is the purpose of a Northern blotting experiment? What types of information can it tell you about the transcription of a gene?
See AnswerQ: Let’s suppose an X-linked gene in mice exists as two
Let’s suppose an X-linked gene in mice exists as two alleles, which we will call B and b. X-chromosome inactivation, a process in which one X chromosome is turned off, occurs in the somatic cells of f...
See AnswerQ: The method of Northern blotting is used to determine the amount and
The method of Northern blotting is used to determine the amount and size of a particular RNA transcribed in a given cell type. Alternative splicing (discussed in Chapter 12) produces mRNAs of differen...
See AnswerQ: In the Western blot shown here, proteins were isolated from red
In the Western blot shown here, proteins were isolated from red blood cells and muscle cells from two different individuals. One individual was unaffected, and the other suffered from a disease known...
See AnswerQ: In the procedure in Figure 22.1, why was it
In the procedure in Figure 22.1, why was it necessary to link the coding sequence for the A or B chains to the sequence for β-galactosidase? How were the A or B chains separate...
