DNA & DNA Replication

Front

What are the building blocks of DNA?

Back

Nucleotides are the building blocks of DNA.

Front

What is the result of DNA replication?

Back

DNA replication results in two DNA molecules, each with one new strand and one original strand.

Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds join nitrogenous bases in DNA.

Front

What are the three components of a nucleotide?

Back

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

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the role of DNA helicase in DNA replication?

Back

DNA helicase unwinds the double helix structure of DNA during replication.

Front

What is the function of DNA polymerase?

Back

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

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 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 semi-conservative replication?

Back

Semi-conservative replication means that each new DNA molecule consists of one original strand and one newly synthesized strand.
