DNA Replication

Front

What is DNA replication?

Back

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

Front

Why is it crucial for living things to replicate their DNA?

Back

Each cell must have its own DNA to function properly and carry out its specific roles.

Front

What are the nitrogenous bases found in DNA?

Back

The nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds join nitrogenous bases in DNA.

Front

In DNA, adenine pairs with which base?

Back

Adenine pairs with thymine (A-T) in DNA.

Front

In DNA, cytosine pairs with which base?

Back

Cytosine pairs with guanine (C-G) in DNA.

Front

What is the role of helicase in DNA replication?

Back

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

Front

What is the significance of the 5' and 3' ends of DNA strands?

Back

The 5' and 3' ends indicate the directionality of the DNA strands, which is important for replication and transcription.

Front

What is the leading strand in DNA replication?

Back

The leading strand is the DNA strand that is synthesized continuously in the same direction as the replication fork.
