DNA Replication

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA, resulting in two identical DNA molecules.

Front

What are the main components of DNA?

Back

DNA is made up of nucleotides, which consist of a deoxyribose sugar, a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine).

Front

What is the structure of DNA?

Back

DNA has a double helix structure, resembling a twisted ladder with two strands running in opposite directions.

Front

What pairs with adenine in DNA?

Back

Thymine pairs with adenine through hydrogen bonds.

Front

What pairs with cytosine in DNA?

Back

Guanine pairs with cytosine through hydrogen bonds.

Front

What is the role of DNA polymerase in replication?

Back

DNA polymerase is an enzyme that 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 helicase in DNA replication?

Back

Helicase is an enzyme that unwinds and separates the two strands of the DNA double helix.

Front

What is a replication fork?

Back

A replication fork is the area where the DNA double helix is unwound and replication occurs.

Front

What is the importance of complementary base pairing in DNA replication?

Back

Complementary base pairing ensures that the new DNA strands are accurate copies of the original strands.
