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

Nucleotides are the building blocks of DNA.

Front

What are the components of a nucleotide?

Back

A nucleotide is composed of a sugar, a phosphate group, and a nitrogen base.

Front

What does DNA stand for?

Back

DNA stands for Deoxyribonucleic acid.

Front

Where is DNA primarily located in a cell?

Back

DNA is primarily located in the nucleus of a cell.

Front

What is the role of hydrogen bonds in DNA?

Back

Hydrogen bonds hold the two strands of DNA together by connecting complementary nitrogen bases.

Front

What are the four nitrogen bases found in DNA?

Back

The four nitrogen bases in DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

How do the nitrogen bases pair in DNA?

Back

Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What happens during DNA replication?

Back

During DNA replication, the DNA molecule unwinds and separates into two strands, each serving as a template for a new strand.

Front

What is semi-conservative replication?

Back

Semi-conservative replication means that each new DNA molecule consists of one old strand and one new strand.
