Structure of DNA

Front

What is the structure of DNA?

Back

DNA is a double helix made up of two strands that wind around each other, consisting of nucleotides.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a phosphate group, a deoxyribose sugar, and a nitrogen base.

Front

What are the four nitrogen bases in DNA?

Back

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

Front

How do nitrogen bases pair in DNA?

Back

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

Front

What is the role of deoxyribose sugar in DNA?

Back

Deoxyribose sugar is part of the nucleotide structure and forms the backbone of the DNA strand.

Front

What type of molecule is DNA?

Back

DNA is a nucleic acid that carries genetic information.

Front

Where is DNA located in a cell?

Back

DNA is primarily located in the nucleus of eukaryotic cells.

Front

What is the function of DNA?

Back

The function of DNA is to store and transmit genetic information that determines an organism's traits.

Front

What is a gene?

Back

A gene is a segment of DNA that contains the instructions for making a specific protein.

Front

What is replication in the context of DNA?

Back

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