6) ene expression controlled by the epigenome is flexible because the epigenome can respond to environmental signals

Select one:

a) in a time-dependent manner.

b) because the chemical bonds in methyl groups can readily bend.

c) by changing the DNA sequences of genes.

d) similarly to the way that the food supply controls appetite.

e) in a way that is completely unpredictable.

7) Which of the following can be determined from the DNA fingerprint of an individual?

A DNA fingerprint can reveal

Select one or more:

a) the indvidual's gender (male or female).
the individual's gender (male or female).

b) the individual's blood type.

c) the individual's biological family relationships (paternity, etc.).

d) how many siblings (brothers and sisters) are found in the family of the individual whose DNA is sampled.

e) the individual’s risk of heart disease.

8) CODIS is the FBI abbreviation for a database containing the

Select one or more:

a) digital images of convicted felons.

b) skin fingerprints of convicted felons.

c) genome sequence from the Human Genome Project.

d) DNA libraries available from published research findings.

e) DNA fingerprints of convicted offenders, arrestees, and crime scene samples.

9) Do identical twins have identical skin fingerprints?

Select one:

a) No, because the twins' skin fingerprints are left-right mirror images of each other due to the mirror image symmetry that happens when identical embryos split apart from one original embryo.

b) It depends. If the identical twins are in the same placenta, they will have the same fingerprints. If they are in separate placentas, they will have different fingerprints.

c) Yes, because identical twins have the same genome and genes they will have identical skin fingerprints.

d) No, because the development of the skin fingerprints are influenced by the environment in the uterus.

e) Yes, because the twins' skin fingerprints are inherited directly from the mother without a contribution from the father.

10 )

Select one:

a) The methylation of the adult nucleus must be removed so that the cloned zygote can become a viable embryo and fetus.

b) Dolly's epigenome was a mixture of the epigenomes of the donor mother and of the egg cell from the surrogate mother.

c) The epigenome of the adult nucleus directs development of the cloned zygote.

d) The epigenome of the female surrogate that carried the pregnancy to term becomes impinted on the genome of the cloned zygote.

e) The epigenome of the egg cell nucleus is transferred to the donor cell nucleus.

In the process of Somatic Cell Nuclear Transfer in which Dolly the sheep was cloned, an adult nucleus was inserted into a denucleated egg cell. How is the epigenome related to this process?
