Question

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? mtdna analysis y - chromosome analysis str analysis pcr analysis

Explanation:

STR analysis (Short Tandem Repeat analysis) is a common forensic technique. It involves analyzing specific regions of DNA (STR loci) that have short repeated sequences. By comparing the STR profiles of the blood sample from the crime scene and the suspect's DNA sample, forensic scientists can determine if they match. mtDNA analysis is more for maternal lineage, Y - chromosome analysis is for male - specific (and not useful if the suspect's gender isn't known in a general sense for this basic comparison), and PCR (Polymerase Chain Reaction) is a technique to amplify DNA but not the specific process for comparison here.

Answer:

STR analysis
