BIO100 Chapter 12 Cell Division and Genetics Lecture
Notes
Of these steps, which occurs first in the production of a recombinant plasmid? - ANS✔✔
isolation of a plasmid from a bacterium
Molecular biologists have perfected DNA fingerprinting so that it is possible to use the
technique to provide evidence to solve crimes and even identify a child's parents. Recently, a
U.S. immigrant asked the U.S. Citizenship and Immigration Services for permission to have her
young daughter who was living with grandparents in their homeland join her. Her request was
denied because there was an apparent mix-up with the child's birth certificate and it could not
be used as proof of maternity. Proof is required in cases such as this. The mother requested
DNA fingerprinting to make her case. Samples of DNA were taken from the mother (Mom) and
daughter (D1) as well as from another daughter (D2) and a son (S) living in the United States
with her. Tandem repeat analysis was run on the four samples, and the results are shown here.
The short tandem repeat analysis ______. - ANS✔✔ compares repetitive DNA sequences from
different individuals
Which enzyme is used to bind DNA fragments together? - ANS✔✔ DNA ligase
The human genome contains approximately ______ genes. - ANS✔✔ 21,000
In human gene therapy, - ANS✔✔ normal versions of genes are transferred to patients who
carry a mutated allele.
Which of these is a genetically modified organism? - ANS✔✔ an organism carrying a gene that
was acquired by artificial means
