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 receives a complete set of genetic information.

Front

What are the main components of DNA?

Back

The main components of DNA are deoxyribose sugar, phosphate groups, and nitrogenous bases (adenine, thymine, cytosine, and 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 are the nitrogenous bases in DNA?

Back

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

Front

How do nitrogenous bases pair in DNA?

Back

In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G) through hydrogen bonds.

Front

What is the role of DNA polymerase?

Back

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

Front

What is the function of the DNA backbone?

Back

The DNA backbone, made of deoxyribose sugar and phosphate, provides structural support and stability to the DNA molecule.

Front

What holds the two strands of DNA together?

Back

The two strands of DNA are held together by hydrogen bonds between the paired nitrogenous bases.

Front

Why is DNA replication important?

Back

DNA replication is crucial because it ensures that each new cell has an identical copy of the DNA, which is necessary for proper cell function and growth.

Front

What is the role of helicase in DNA replication?

Back

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