Question

Suppose a suspicious hair was found in a victim's home. a gel is set up with the dna fragments of two suspected criminals in lanes 4 and 5, the dna fragments of the suspicious hair in lane 3, and the victim's dna fragments, as a negative control, are in lane 2. a dna ladder is in lane 1. the resulting gel is below. which suspect, if any, committed the crime? explain your answer.

Answer 1

Explained

Step-by-step explanation:

None of the suspectswere responsible for the crime.Most of the Genome contains two versions of the marker as human is diploid.If any of the victims have committed the crime,the victim hair markers must match the suspect's markers.

From the gel we see clearly that suspicious hair markers do not match the markers of suspicious criminals. Instead, it matched the fragments of the victim's DNA(as lane 2 & 3 bands are the same). Suspicious hair is the hair of the suspect.
