Which DNA fingerprinting technique examines the length variation of DNA repeat sequences in human DNA?

VNTRs (variable tandem repeats)

PCR (polymerase chain reaction) analysis

STRs (short tandem repeats)

mtDNA (mitochondrial DNA) analysis

the answer is A. on edgenui ty

The correct answer is Variable Tandem Repeats (VNTRs).

Within a gene, short alignments of DNA repeated in tandem known as VNTRs, change largely in numbers among the individuals, also known as microsatellites. It has common application in DNA fingerprinting because of extreme variability between the humans.

These repeats can be witnessed on various chromosomes, and usually, signify changes in length between the individuals. Each of the variants can function as an inherited allele, permitting them to be utilized for parental or personal identification.
