Answer:
3 repeats
Explanation:
PCR technique used to make multiple DNA copies from a segment or small sequence of DNA that is called primer for identification or detection of the pathogen.
given:
Primer amplified base pairs - 130 that are adjacent to - 14 base pair repeats.
PCR product size was 172
So, the extra nucleotide that we get would be = product size - primer amplified
172- 130 = 42 bp
Extra repeats you got = 42/14= 3 repeats
