A)sex chromosomes
B)base pairings
C)short tandem repeats
D)chromosome size
E)DNA/RNA pairing

Question

Quizplus · Accepted Answer

DNA profiling is based on the identification and analysis of short tandem repeats (STRs) in the human genome. STRs are small repeating sequences of DNA that differ in length between individuals, and these differences can be used to create a unique profile for each person. Although sex chromosomes, base pairings, chromosome size, and DNA/RNA pairing can all vary between individuals, they are not used in DNA profiling as they do not provide the necessary level of variation to create unique profiles.
