Question

You are attempting to see if a suspect is associated with a crime. The only evidence you have is a tiny drop of blood from the crime scene, which is not enough to run an analysis. How can you increase your crime scene DNA sample

Answer 1

Answer:

There are no options in this question but generally a sample of DNA can be increased;

By using Polymerase Chain Reaction (PCR) technique.

Explanation:

This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.

In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.
