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

Explanation:

PCR (Polymerase Chain Reaction) analysis is often the first - step in DNA analysis to amplify the DNA sample for further examination. STR (Short Tandem Repeat) analysis is a common method used in forensic science to compare DNA samples and determine if they match. mtDNA (mitochondrial DNA) analysis is useful for samples with low amounts of DNA but is less specific for individual identification compared to STR. Y - chromosome analysis is mainly used for male - related genetic investigations. In this case of comparing a crime - scene blood sample to a suspect's DNA, STR analysis is most commonly used for individual identification.

Answer:

C. STR analysis
