Question

What sections of DNA are used in DNA fingerprinting

A. Sections that are made by bacteria

B. Sections that only contain mRNA

C. Sections that are unique to each person

D. Sections that have the fewest mutations

Answer 1

In DNA fingerprinting, the sections of DNA used are sections that are unique to each person. These unique sections have different sequences in each individual, allowing for identification through DNA analysis.

Step-by-step explanation:

In DNA fingerprinting, the sections of DNA that are used are sections that are unique to each person. These sections have different sequences in each individual, making them useful for identifying individuals. DNA fingerprinting relies on the technique of Restriction Fragment Length Polymorphism (RFLP) which involves cutting the DNA into fragments using restriction enzymes, separating them by gel electrophoresis, and analyzing the patterns of the fragments.

Answer 2

The particular polymorphism normallyused for DNA fingerprinting is the Short Tandem Repeats (STRs) which are non-conding portions of DNA that consist of a repeating genetic sequence of DNA code.
