DNA Structure and Replication

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase replicates the new DNA continuously along the leading strand.

Front

Which base does adenine bond with in DNA?

Back

Adenine bonds with thymine.

Front

Which base does guanine bond with in DNA?

Back

Guanine bonds with cytosine.

Front

What are the building blocks of DNA?

Back

Nucleotides are the units that are repeatedly joined together to form a strand of DNA.

Front

What are pyrimidines in the context of DNA?

Back

Pyrimidines are smaller, single-ringed bases such as thymine and cytosine.

Front

What are purines in the context of DNA?

Back

Purines are larger, double-ringed bases such as adenine and guanine.

Front

What is the structure of a nucleotide?

Back

A nucleotide consists of a phosphate group, a sugar (deoxyribose in DNA), and a nitrogenous base.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate replication and transcription of genetic information.

Front

What is the difference between the leading and lagging strands during DNA replication?

Back

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

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands to allow replication.
