You are a researcher studying the genetic basis of colon cancer. You
have been working with a colon cancer cell line to determine the
expression levels of different genes that might contribute to cancer
formation. You obtain the DNA methylation status of five genes of
interest (the data is shown in the table below). The plus (+) sign
indicates the level of DNA methylation; more plus signs correlate with
increased methylation levels.
- Based on the information shown above, which gene would you predict
to have the highest rate of transcription? CORRECT ANSWER +
- greater methylation yields more heterochromatin; thus, reduces its
legability.
Which of the following criteria are critical to DNA's ability to act as the
genetic material? (CHOOSE ALL THAT APPLY)
Must replicate faithfully
Must encode a phenotype
Must contain complex information
Must be linear
,Must have the capacity to vary CORRECT ANSWER Must
replicate faithfully
Must encode a phenotype
Must contain complex information
Must have the capacity to vary
The Hershey-Chase experiments demonstrated that
protein is the genetic material.
the genetic code codes for protein.
DNA is a double helical structure.
DNA is the genetic material. CORRECT ANSWER DNA is the
genetic material.
Which of the following statements is false?
DNA contains the nitrogenous bases A, T, C, and G
The genetic code is determined by the order of the bases.
Nucleotides contain sulfur
Nucleotides contain a sugar component CORRECT ANSWER
Nucleotides contain sulfur
True or False:
Rare alleles are always recessive. CORRECT ANSWER True
,One Parent is a carrier of the sickle cell trait and the other is normal.
What is the probability that their child has sickle-cell disease?
25%
50%
75%
100%
0% CORRECT ANSWER 0%
You perform a chi-squared test to determine if your observed data
support your null-hypothesis. Your P value = 0.1. What can you
conclude?
It is inconclusive
You reject your null hypothesis
You cannot reject your null hypothesis CORRECT ANSWER
You cannot reject your null hypothesis
Solid black, black with tan belly, and agouti coat color in mice are all
caused by alleles of the agouti gene. All three colors can be true-
breeding. When using mice from true-breeding strains: (1) Black ×
Agouti F1s are all agouti, (2) Black × Black with Tan belly F1s are all
black and tan, and (3) Black with Tan belly × Agouti F1s are all agouti.
If you were to cross the F1s from (1) with the F1s from (2), what
proportion of the resulting offspring would you expect to be black with a
tan belly?
, (input your answer as a decimal not a fraction, for example if your
answer was 1/8 you would input 0.125) CORRECT ANSWER
0.25
Genes A and B are closely linked. A man with genotype AaBb, who
inherited Ab from his mother, has a son with a woman who is
homozygous recessive. What is the likelihood that the son is
homozygous recessive like his mother?
100%
more information is needed.
0%
greater than 25%
25%
less than 25% CORRECT ANSWER less than 25%
If you want to determine recombination frequencies between two linked
traits, what is the most useful type of cross that you can perform with the
F1 progeny to figure out the genetic distance between the two genes?
a dihybrid cross
A crossover
a back cross to the homozygous dominant parent
test cross CORRECT ANSWER test cross
True or False
