In DNA profiles,the pattern of bands is _____.
A) due to variations in restriction enzyme recognition sites in plasmid DNA
B) identical in all individuals
C) due to variations in STR alleles between individuals
D) due to the presence of transgenes
E) possible only when copious quantities of DNA are available

Question

Quizplus · Accepted Answer

The pattern of bands in DNA profiles is due to variations in STR (short tandem repeat) alleles between individuals. STRs are regions of DNA that contain repeating units of nucleotides. The number of repeats can vary between individuals, resulting in different banding patterns on a gel. Therefore, DNA profiles can be used to distinguish between individuals based on their unique banding patterns.
