Front

What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix.

Front

What role does DNA play in living organisms?

Back

DNA serves as the blueprint for traits of all living things.

Front

What type of bonds hold the two strands of DNA together?

Back

The two strands of DNA are held together by hydrogen bonds.

Front

What are the components of a nucleotide?

Back

A nucleotide is made up of a sugar, phosphate, and a nitrogenous base.

Front

What is the complementary DNA strand for 5'-ATGCCAT-3'?

Back

The complement to the DNA strand 5'-ATGCCAT-3' is 3'-TACGGTA-5'.

Front

What are the four types of nitrogenous bases in DNA?

Back

The four types of nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

How do adenine and thymine pair in DNA?

Back

Adenine pairs with thymine through two hydrogen bonds.

Front

How do cytosine and guanine pair in DNA?

Back

Cytosine pairs with guanine through three hydrogen bonds.

Front

What is the significance of the double helix structure of DNA?

Back

The double helix structure allows for the compact storage of genetic information and provides stability.

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a DNA molecule makes a copy of itself before cell division.
