DNA Structure and Replication

Front

What is the structure of DNA called?

Back

Double helix.

Front

What are the building blocks of DNA?

Back

Nucleotides.

Front

Which nitrogenous base pairs with Guanine?

Back

Cytosine.

Front

Which nitrogenous base pairs with Adenine?

Back

Thymine.

Front

What are the two types of nitrogenous bases in DNA?

Back

Purines (Adenine and Guanine) and Pyrimidines (Cytosine and Thymine).

Front

What is the process of copying DNA called?

Back

DNA replication.

Front

What is the role of DNA polymerase in DNA replication?

Back

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

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 function of hydrogen bonds in DNA?

Back

They hold the two strands of the DNA double helix together by pairing nitrogenous bases.

Front

What is the complementary base pairing rule in DNA?

Back

Adenine pairs with Thymine, and Guanine pairs with Cytosine.
