1.
Which statement best describes DNA sequencing?
A single-base difference between individuals — the commonest kind of genetic variation.
The right to control who sees your genetic information.
Agreeing to a test after understanding fully what it can and cannot reveal.
Determining the exact order of bases in a piece of DNA.
2.
During gel electrophoresis DNA moves towards the:
Negative electrode
Top of the gel
Positive electrode
Well
3.
Why do STRs make useful markers in DNA profiling?
They code for proteins
They are identical in all people
They are only found in mitochondria
The number of repeats varies greatly between individuals
4.
Which statement best describes DNA profiling?
A short single-stranded DNA sequence complementary to the start of the target region, providing a start point for DNA polymerase.
A technique that separates DNA fragments by size as they move through a gel in an electric field.
A technique that makes many copies of a specific DNA sequence by repeated cycles of heating and cooling.
Comparing the pattern of variable DNA regions (e.g. short tandem repeats) between individuals.
