restriction enzymes
polymerase enzymes
|
Which technique is used to separate DNA fragments by size during genetic fingerprinting?

PCR
|
What binds to complementary VNTR sequences during the hybridisation step?
restriction enzymes
specific radioactive or fluorescent probes
DNA ligase
DNA polymerase
|
If radioactive probes are used during genetic fingerprinting, what is taken during the development stage?
UV light images
microscope images
X-ray images
photographs
|
What determines the probability of a match in genetic fingerprinting?
the number of matching bands
the size of the DNA fragments
the type of probe used
the number of restriction enzymes used
|
Which of the following is NOT a key use of genetic fingerprinting technology?
establishing paternity
treating genetic disorders
identifying suspects from crime scene DNA
diagnosing genetic disorders
|
What is the role of VNTRs in genetic fingerprinting?
they are used to cut the DNA into fragments
they are used to amplify the DNA
they are the basis for the distinctiveness of an individual's DNA sequence
they are used to separate the DNA fragments by size
|
What is the purpose of using probes in genetic fingerprinting?
to bind to complementary VNTR sequences
to amplify the DNA
to cut the DNA into fragments
to separate the DNA fragments by size
|
What is the relationship between the number of matching bands and the likelihood that the fingerprints are from the same individual?
the higher the number of matching bands, the greater the likelihood
the higher the number of matching bands, the lower the likelihood
the relationship depends on the type of probe used
there is no relationship between the number of matching bands and the likelihood
