DNA Structure & Replication

Front

What is the role of Helicase in DNA replication?

Back

Helicase is the enzyme responsible for unzipping the double helix of DNA, separating the two strands to allow replication to occur.

Front

What is the first step of DNA replication?

Back

The first step of DNA replication is when DNA Helicase unwinds the original DNA strand.

Front

Which base does Adenine bond with in DNA?

Back

Adenine bonds with Thymine.

Front

What is the second step of DNA replication?

Back

The second step of DNA replication is when DNA polymerase builds new strands by bringing in new nucleotide bases.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

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 is the function of DNA polymerase?

Back

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

Front

What is the role of Ligase in DNA replication?

Back

Ligase is the enzyme that joins together the Okazaki fragments on the lagging strand, sealing the gaps between newly synthesized DNA.

Front

What is the significance of the antiparallel structure of DNA?

Back

The antiparallel structure of DNA allows for the complementary base pairing and proper functioning of enzymes during replication.

Front

What is a replication fork?

Back

A replication fork is the area where the DNA double helix is unwound and separated into two single strands during replication.
