|
What binds to complementary VNTR sequences during the hybridisation step?

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