Front

What is the function of a restriction enzyme?

Back

To search for specific sequences in DNA and cut them at designated locations.

Front

Back

Thymine

Front

What are the three components of a nucleotide?

Sugar, phosphate, nitrogen base.

Front

What is the role of DNA in living organisms?

Back

To store and transmit genetic information.

Front

What is the base pairing rule in DNA?

Back

Adenine pairs with Thymine, and Guanine pairs with Cytosine.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is the process of DNA replication?

Back

The process by which a DNA molecule makes a copy of itself.
