DNA Structure and Replication

Front

What is DNA made up of?

Back

Nucleotides are the building blocks of DNA.

Front

In DNA, what base always pairs with A?

Back

The base that always pairs with A (adenine) is T (thymine).

Front

What does DNA stand for?

Back

DNA stands for Deoxyribonucleic acid.

Front

What is the complementary nucleotide sequence for CCC - ACT - GGG?

Back

The complementary sequence is GGG - TGA - CCC.

Front

Where is DNA located in eukaryotic cells?

Back

DNA is located in the nucleus of eukaryotic cells.

Front

What are the three components of a nucleotide?

Back

A nucleotide consists of a phosphate group, a sugar (deoxyribose), and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What is the process of DNA replication?

Back

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

Front

What enzyme is responsible for unwinding the DNA double helix during replication?

Back

The enzyme responsible for unwinding the DNA double helix is helicase.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.
