Unit 4 - DNA Structure and DNA Replication

Front

What is DNA Polymerase?

Back

An enzyme responsible for adding nucleotides during DNA replication.

Front

What are nucleotides?

Back

Building blocks of DNA and RNA, consisting of a sugar, phosphate, and nitrogen base.

Front

Where does DNA replication occur in a cell?

Back

In the nucleus.

Front

What is the structure of a nucleotide?

Back

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

Front

What happens during DNA replication?

Back

The DNA makes an exact copy of itself.

Front

What is the role of Primase in DNA replication?

Back

Primase synthesizes a short RNA primer to initiate DNA synthesis.

Front

What is the function of Ligase in DNA replication?

Back

Ligase joins Okazaki fragments on the lagging strand during DNA replication.

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.

Front

What are the nitrogenous bases found in DNA?

Back

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

Front

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

Back

The double helix structure allows for the stable storage of genetic information and facilitates replication.
