DNA Replication

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA, allowing genetic information to be passed on during cell division.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is a complementary base pair?

Back

A complementary base pair is a pair of nitrogenous bases that bond together in DNA, specifically Adenine with Thymine and Cytosine with Guanine.

Front

What role does DNA helicase play in DNA replication?

Back

DNA helicase is the enzyme that unwinds and separates the two strands of the DNA double helix during replication.

Front

What is the function of DNA polymerase?

Back

DNA polymerase is the enzyme responsible for adding free nucleotides to the growing DNA strand during replication.

Front

What is a replication fork?

Back

A replication fork is the Y-shaped region where the DNA double helix is unwound and replicated.

Front

How does DNA replication ensure accuracy?

Back

DNA replication ensures accuracy through the proofreading function of DNA polymerase, which checks and corrects errors in nucleotide pairing.

Front

What is the significance of genetic diversity?

Back

Genetic diversity is important for the survival and adaptability of species, allowing for variations that can enhance survival in changing environments.

Front

What is the difference between ribose and deoxyribose?

Back

Ribose is a sugar found in RNA, while deoxyribose is a sugar found in DNA, lacking one oxygen atom compared to ribose.
