What is the purpose of Electrophoresis in DNA analysis?

Back

It is a method of separating DNA molecules according to their size and electrical charge.

How can DNA Fingerprinting be used in paternity testing?

Back

By comparing the DNA profiles of a child and potential fathers, one can determine biological relationships.

Front

What are the main components of DNA?

Back

DNA is composed of nucleotides, which include a phosphate group, a sugar (deoxyribose), and a nitrogenous base.

Front

What role do restriction enzymes play in DNA Fingerprinting?

Back

Restriction enzymes cut DNA at specific sequences, allowing for the analysis of different DNA fragments.

Front

What is a DNA probe?

Back

A DNA probe is a fragment of DNA used to detect the presence of complementary sequences in a sample.

Front

What is the significance of the Polymerase Chain Reaction (PCR) in DNA analysis?

Back

PCR is a technique used to amplify small segments of DNA, making it easier to analyze.

Front

What does it mean if two individuals have similar DNA profiles?

Back

It suggests that they may be closely related or share a common ancestor.

Front

What is the role of gel electrophoresis in DNA Fingerprinting?

Back

Gel electrophoresis is used to separate DNA fragments based on size, allowing for comparison of DNA profiles.

Front

What is a genetic marker?

Back

A genetic marker is a specific DNA sequence with a known location on a chromosome that can be used to identify individuals.
