DNA Structure and DNA Replication

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA before cell division.

Front

When does DNA replication occur?

Back

Before cell division.

Front

What are nitrogen-containing bases in DNA?

Back

Molecules that include adenine (A), thymine (T), cytosine (C), and guanine (G), which pair together to form the rungs of the DNA ladder.

Front

What makes up the rungs (steps) of a DNA ladder?

Back

Nitrogen bases.

Front

What is the complement to the DNA strand 5'-ATGCCAT-3'?

Back

3'-TACGGTA-5'.

Front

What is the structure of DNA?

Back

A double helix formed by two strands of nucleotides, with a sugar-phosphate backbone and nitrogen bases in the center.

Front

What are nucleotides?

Back

The building blocks of DNA, consisting of a sugar, a phosphate group, and a nitrogen base.

Front

What role do hydrogen bonds play in DNA?

Back

They hold the two strands of DNA together by connecting the nitrogen bases.

Front

What determines the specific traits in an organism?

Back

The sequence of nucleotide bases in the DNA molecule.

Front

What is the function of DNA?

Back

To store and transmit genetic information.
