Question

Someone who has fewer repeats of the 16bp repeat found at the d1s80 locus is going to have their DNA travel

a) Faster
b) Slower
c) Sideways
d) Instantly

Answer 1

Someone with fewer 16bp repeats at the d1s80 locus will have DNA that travels faster during gel electrophoresis due to shorter fragment length.

Step-by-step explanation:

The question asks about the relationship between the number of repeats at the d1s80 locus and how fast DNA travels during gel electrophoresis. Someone with fewer repeats of the 16bp repeat found at the d1s80 locus will have DNA that travels faster through the gel. This is because shorter DNA fragments move more easily through the porous matrix of the gel, whereas longer fragments with more repeats are hindered and travel slower. This principle is exploited in DNA fingerprinting and other genetic analyses where DNA fragments are separated based on size.
