Gel Electrophoresis

In DNA isolation lab, what was the purpose of the detergent

Dissolve the cell and nuclear membrane

Scientists are able to produce millions of copies of specific DNA sequence from a small amount of DNA through the process of:

Polymerase Chain Reaction (PCR)

What is not found in DNA

chromosomes

The smaller the DNA fragment, the

further it moves down the gel

What type of chemical bond is found between paired bases of the DNA double helix.

Hydrogen

In DNA profiling by gel electrophoresis, DNA is separated on the basis of?

Number of base pairs (BP)

What is in a nucleotide

phosphate group, sugar (deoxyribose), nitrogenous bases

Gel Electrophoresis is used to separate the fragments of DNA. The larger pieces of DNA will travel

slower than the smaller fragments that go through the gel quicker

What property of DNA causes it to migrate to the positive pole of the electrophoresis apparatus

the negative charge of the DNA
