A Barr Body is:

• The activated X chromosome in a female

• The activated X chromosome in a male

• The inactivated X chromosome in a female

• The inactivated X chromosome in a male

Methyl groups attach to which base?

• thymine

• adenine

• uracil

• cytosine

methylation has what effect upon gene expression?

• enhances gene expression

• speeds up gene expression

• silences gene expression

Acetylation of the histone tails results in:

• "loosens" the DNA so that it is available for transcription

• "tightens" the DNA so that it is not available for transcription; in effect the gene expression is "silenced"

Hypermethylation of CpG islands can result in cancer because

• tumor suppressor genes are "silenced"

• oncogenes are "silenced"

What is the effect when the Avy gene is methylated in mice?

• the mice are yellow and overweight

• the mice are brown with normal weight

• the mice are yellow and normal weight

• the mice are brown and overweight
