Homologous regions of DNA can vary slightly in base-pair composition among individuals in a population.When a homologous stretch of DNA is cut with restriction enzymes in different individuals,fragments of different lengths are produced.These fragments are called
A)landmarks of DNA sequencing.
B)contig fragments.
C)single length polymorphisms.
D)restriction fragments length polymorphisms.
E)sequence-tagged site fragments.

Question

Quizplus · Accepted Answer

The fragments produced by cutting homologous DNA stretches with restriction enzymes in different individuals with varying base-pair composition are called restriction fragments length polymorphisms (RFLPs). RFLPs can be used as genetic markers in population and forensic studies.
