Question

Identify the incorrect statement representing the feature of restriction fragment length polymorphism.

• A. They can be used to detect single gene mutations in human DNA.
• B. They can be used prenatally to analyze fetal cells for genetic disorders.
• C. They can be used to amplify large quantities of a single gene through use of the polymerase chain reaction.
• D. They can be used to detect variation in DNA sequences among individuals.
• E. They can be separated by electrophoresis according to fragment size.

Answer 1

The correct option is C They can be used to amplify large quantities of a single gene through use of the polymerase chain reaction.

Restriction fragment length polymorphism is the process by which DNA fragments are mapped according to their restriction size by gel electrophoresis. They can be used to check for mutations in DNA in foetal cells and variations in DNA.

So the correct answer is "they can be used to amplify large quantities of a single gene through use of the polymerase chain reaction".
