Short tandem repeats (STRs)
A)are useful in identifying specific individuals.
B)are important sites in vectors where foreign DNA can be integrated.
C)are errors that can arise during DNA sequencing.
D)are DNA fragments generated during PCR.

Question

Quizplus · Accepted Answer

Short tandem repeats (STRs) are specific DNA sequences that are repeated in a pattern and vary between individuals. They are useful in forensic analysis and paternity testing for identifying specific individuals based on their unique STR profiles.

B, C, and D are incorrect:
B) While vectors can contain repeated DNA sequences, STRs specifically refer to sequences in the host organism's DNA.
C) Errors during DNA sequencing can refer to a variety of issues, but STRs are not themselves an error.
D) PCR amplifies specific target DNA sequences, including STRs, but the STRs themselves are not "fragments" generated during PCR.
