DNA Structure and Replication

Front

What are Okazaki fragments?

Back

Short sequences of DNA nucleotides synthesized on the lagging strand during DNA replication.

Front

On which strand do Okazaki fragments form?

Back

Lagging strand.

Front

What base does Guanine bond with?

Back

Cytosine.

Front

What is the role of helicase in DNA replication?

Back

It unzips the DNA double helix to prepare for replication.

Front

What are nucleotides made up of?

Back

A sugar, phosphate, and a nitrogenous base.

Front

In which direction is DNA replicated?

Back

5' to 3' direction.

Front

What is the function of DNA polymerase?

Back

It synthesizes new DNA strands by adding nucleotides to a growing chain.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine, Thymine, Cytosine, and Guanine.

Front

What is the structure of DNA?

Back

A double helix formed by two strands of nucleotides.

Front

What is the significance of the 5' and 3' ends of DNA?

Back

They indicate the directionality of the DNA strands, crucial for replication and transcription.
