DNA Replication

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA, ensuring that each new cell receives a complete set of genetic information.

Front

What are the main enzymes involved in DNA replication?

Back

The main enzymes involved in DNA replication are DNA helicase (unwinds the DNA double helix), DNA polymerase (synthesizes new DNA strands), and DNA ligase (joins Okazaki fragments on the lagging strand).

Front

What is the role of DNA helicase in DNA replication?

Back

DNA helicase unwinds the double helix structure of DNA, separating the two strands to allow for replication.

Front

What base pairs with adenine in DNA?

Back

Thymine pairs with adenine in DNA.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is the part of the cell cycle where DNA replication occurs, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What is the complementary DNA strand for the sequence ATG TGA CAG?

Back

The complementary DNA strand is TAC ACT GTC.

Front

What is the function of DNA polymerase during replication?

Back

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

Front

What is the term for the regions where DNA is unwound during replication?

Back

The regions where DNA is unwound are called replication forks.

Front

What is the role of cytosine in DNA?

Back

Cytosine is one of the four main bases in DNA and pairs with guanine.

Front

What happens if DNA replication is not accurate?

Back

If DNA replication is not accurate, it can lead to mutations, which may result in genetic disorders or cancer.
