DNA Structure and Replication

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, resembling a twisted ladder.

Front

What are the building blocks of DNA?

Back

DNA is made up of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

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

How do nitrogenous bases pair in DNA?

Back

Adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G) through hydrogen bonds.

Front

What forms the sides of the DNA ladder?

Back

The sides of the DNA ladder are made up of alternating sugar and phosphate groups.

Front

What is the role of hydrogen bonds in DNA?

Back

Hydrogen bonds hold the nitrogenous bases together, stabilizing the DNA structure.

Front

What is DNA replication?

Back

DNA replication is the process by which a DNA molecule makes a copy of itself before cell division.

Front

What enzyme is primarily responsible for DNA replication?

Back

DNA polymerase is the enzyme that synthesizes new DNA strands during replication.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate replication and transmission of genetic information.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.
