Chapter 12 DNA Analysis Checkpoint Answers
1. In the nucleus of the cell
2. Wrapped around the chromosomes
3. A gene is a smaller portion of the chromosome, both
of which are portions of the DNA molecule that is
packed into the nucleus.
4. The Human Genome Project is a unified effort to
identify and determine the sequence of all genes
found on the human chromosome.
5. The nucleus
6. Adenine, guanine, cytosine, thymine
7. The phosphate groups give DNA its acidic properties.
8. Blood, semen, saliva, hair follicular tissue, bone
9. Restriction Fragment Length Polymorphism
10.
To cut the DNA into smaller fragments
11.
Probably not; the sequence may be different, but
the number of base pairs may be the same, making
the fragment length the same.
12.
PCR can make many copies of DNA, which can
then undergo characterization and analysis.

13.
In RLFP, between sequences; in PCR,
lengthwise between bases (“unzipped”)
14.
In RFLP, with restriction enzymes; in PCR, heat.
15.
To begin the replication in the process of PCR
16.
To identify shorter sequences after RFLP has
been performed
17.
The FBI Lab’s Combined DNA Index System
(CODIS) is used by law enforcement agencies.
18.
The forensic index is a DNA database formed
with DNA from crime scenes; the offender index is a
DNA database formed with the DNA of criminal
offenders.
19.
Mitochondrial DNA comes from the mitochondria
in the cell. It can be obtained from older or more
degraded and/or smaller samples.
20.
Nuclear DNA is inherited from both mother and
father; mitochondrial DNA is inherited from the mother
only.
