Question 2

STR analysis can also be used for crime scene investigations in addition to maternity testing.Suppose that the results for the Mom were found at a crime scene,that the daughter's and the son's results were from possible suspects,and that each of the DNA markers in the gel was an STR marker.Would these results be enough to convince a jury that the results from the daughter matched the crime scene DNA (Mom)?

Accepted Answer

A) Yes,because the two STR markers match in size. 
B) Yes,because you need only one STR marker to match to definitely make a connection between two people's DNA. 
C) No,because even though two STR markers matched,there still could be mismatches in the other 11 markers. 
D) No,because blood-typing data analysis was not performed. 
A) Yes,because the two STR markers match in size. 
B) Yes,because you need only one STR marker to match to definitely make a connection between two people's DNA. 
C) No,because even though two STR markers matched,there still could be mismatches in the other 11 markers. 
D) No,because blood-typing data analysis was not performed.

Question 5

The following figure shows that gel electrophoresis can be used to separate repetitive DNA sequences.Gel electrophoresis separates DNA fragments because ________.

Accepted Answer

A) double-stranded moves slower than single-stranded DNA 
B) of ratios of guanine to cytosine 
C) the DNA fragments have different lengths 
D) of the salt concentration in the gel matrix 
A) double-stranded moves slower than single-stranded DNA 
B) of ratios of guanine to cytosine 
C) the DNA fragments have different lengths 
D) of the salt concentration in the gel matrix

Question 6

Based on the data in the graph,do you think Bt corn is having its intended effect?

Accepted Answer

A) Yes,because Bt corn affected the mortality of all three arthropods equally. 
B) Yes,because Bt corn selectively killed corn borers that ate it while the beetles and mites were unaffected when eating the Bt corn as compared to the non-Bt corn. 
C) No,because Bt corn was designed to kill all arthropods that ate it,and only the corn borers were killed after eating the Bt corn. 
D) No,because corn borer percent mortality increased when corn borers ate Bt corn; if Bt corn was effective,then percent mortality should have decreased. 
A) Yes,because Bt corn affected the mortality of all three arthropods equally. 
B) Yes,because Bt corn selectively killed corn borers that ate it while the beetles and mites were unaffected when eating the Bt corn as compared to the non-Bt corn. 
C) No,because Bt corn was designed to kill all arthropods that ate it,and only the corn borers were killed after eating the Bt corn. 
D) No,because corn borer percent mortality increased when corn borers ate Bt corn; if Bt corn was effective,then percent mortality should have decreased.

Question 7

The short tandem repeat analysis ________.

Accepted Answer

A) compares markers on the sex chromosomes 
B) compares repetitive DNA sequences from different individuals 
C) does not require DNA amplification 
D) checks for purine and pyrimidine ratios 
A) compares markers on the sex chromosomes 
B) compares repetitive DNA sequences from different individuals

C) The recombinant plasmids are mixed with bacteria. 
D) Bacteria carrying recombinant plasmids are cloned.
