How does DNA fingerprinting distinguish one individual from another?
A) DNA fingerprinting makes use of noncoding sections of DNA that consist of two to five bases repeated over and over again which looks for the number of times such a sequence is repeated.
B) DNA fingerprinting makes use of coding sections of DNA that consist of two to five bases repeated over and over again which looks for the number of times such a sequence is repeated.
C) DNA fingerprinting makes use of noncoding sections of DNA that consist of a single base repeated over and over again which looks for the number of times such a sequence is repeated.
D) DNA fingerprinting makes use of noncoding sections of RNA that consist of two to five bases repeated over and over again which looks for the number of times such a sequence is repeated.
E) DNA fingerprinting makes use of coding sections of RNA that consist of two to five bases repeated over and over again which looks for the number of times such a sequence is repeated.

DNA fingerprinting makes use of noncoding sections of DNA that consist of two to five bases repeated over and over again which looks for the number of times such a sequence is repeated. These sections, known as short tandem repeats (STRs), vary in length and frequency among individuals, making them ideal for identifying unique genetic profiles. By comparing the STR patterns between samples, forensic scientists can distinguish one individual from another, even within closely related individuals.
