DNA Structure and Replication

Front

What organelle is DNA usually found in?

Back

Nucleus

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the shape of the DNA molecule?

Back

The shape of the DNA molecule is a double helix.

Front

What are the components of a nucleotide?

Back

Nucleotides are made of a sugar, a phosphate group, and a nitrogen base.

Front

What is the process called when more DNA is made?

Back

Replication.

Front

What are the four nitrogen bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What base pairs with Adenine in DNA?

Back

Thymine (T) pairs with Adenine (A).

Front

What base pairs with Cytosine in DNA?

Back

Guanine (G) pairs with Cytosine (C).

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.
