DNA replication

Front

What is the enzyme that unzips the DNA to prepare for replication?

Back

Helicase is the enzyme that unwinds and separates the two strands of DNA during replication.

Front

What is the basic unit of DNA?

Back

Nucleotide is the basic building block of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

Which nitrogenous base does Guanine bond with?

Back

Cytosine is the nitrogenous base that pairs with Guanine in DNA.

Front

What is the structure of DNA?

Back

DNA has a double helix structure, resembling a twisted ladder.

Front

What is the order of DNA replication?

Back

The order of DNA replication is: 1. Unwinding of the DNA helix, 2. Complementary base pairing, 3. Formation of new strands, 4. Proofreading and repair.

Front

Is the new DNA strand formed after replication an exact copy of its parent strand?

Back

True, the new DNA strand is an exact copy of its parent strand due to the semi-conservative nature of DNA replication.

Front

What role does DNA polymerase play in DNA replication?

Back

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

Front

What is the function of the replication fork?

Back

The replication fork is the area where the DNA double helix is unwound, allowing for the synthesis of new DNA strands.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are Adenine, Thymine, Cytosine, and Guanine.

Front

What is the significance of hydrogen bonds in DNA?

Back

Hydrogen bonds between nitrogenous bases hold the two strands of DNA together, ensuring the stability of the double helix.
