While investigating a break-in, the police discover that the intruder was cut on the broken window that he or she used to enter the house and left a sample of blood behind. soon after the crime, the police apprehend a suspect and obtain a dna sample. which process is most likely to be used to determine whether the blood on the glass belongs to the suspect?
pcr analysis
str analysis
mtdna analysis
y-chromosome analysis

The correct answer would be STR analysis.

STR or Short Tandem Repeats analysis is one of the commonly used DNA analysis molecular technique.

Short Tandem Repeats are the repeating units of two to thirteen nucleotides present in particular loci on DNA, especially in microsatellite region.

This analysis counts the exact number of repeating units present in different samples based on which it helps in comparing the DNA samples of different individuals.

In forensic science, it is used to compare the DNA found at the crime scene with the DNA of the suspect.

is this a psat question, if so do not cheat try your best.
