All of the following can be achieved through positional cloning, except:
In genetic engineering, auxotrophic bacteria can be used as selectable markers. Which of the following is an advantage of utilizing auxotrophic bacteria in this way?
Suppose you want to study the transfer of a plasmid containing a gene for ampicillin resistance from a donor strain to a recipient strain. Unlike the donor strain which is resistant to ampicillin, the recipient strain is sensitive to ampicillin and lacked the plasmid.
To test the transfer of the plasmid, you perform an interrupted mating experiment where samples are taken at various time intervals and plated on a selective medium containing ampicillin to identify transconjugants.
What will you expect from the number of transconjugants over time provided that the transfer of the plasmid is successful?
Which of the following best describes the term genetic complementation?
A group of four fruit fly mutants (X, Y, Z, and W) was studied for their wing development. Mutant Y fails to complement mutant Z while wild-type recombinants form between mutant W and mutant X. Which of the following groups of mutants have mutations in the same gene?
In a transduction experiment selecting for leu transductants, the minimal medium should lack _________ and therefore __________ compound should be added to the minimal medium.
Defects in the meiotic process are the cause of several human disorders. Which of the following is the most common chromosomal abnormality disorder?
Which of the following is the most likely genotype of the color-blind father in a family where a woman who is wild type (homozygous) and a man with color blindness have a daughter with Turner syndrome (XO) who has normal color vision and blood clotting?
