DNA Structure and Replication

Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds.

Front

What are Okazaki fragments used to elongate?

Back

The lagging strand away from the replication fork.

Front

Which enzyme is responsible for proofreading and removing RNA Primase?

Back

DNA Polymerase 1.

Front

What shape is created by the separation of the two single strands of DNA?

Back

A replication fork.

Front

What is the function of primase in DNA replication?

Back

Primase synthesizes RNA primers needed for DNA polymerase to start replication.

Front

What is the role of DNA Polymerase III?

Back

DNA Polymerase III is responsible for synthesizing new DNA strands by adding nucleotides.

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds and separates the double-stranded DNA.

Front

What is the significance of the leading and lagging strands in DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments called Okazaki fragments.

Front

What is the role of ligase in DNA replication?

Back

Ligase joins Okazaki fragments together to form a continuous DNA strand.

Front

What are the four nitrogenous bases in DNA?

Back

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