DNA structure

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life.

The building blocks of DNA are nucleotides.

A nucleotide is made of a sugar (deoxyribose), a phosphate group, and a nitrogen base.

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

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

The shape of the DNA molecule is a double helix.

The backbone of the DNA structure is formed by deoxyribose (sugar) and phosphate.

The function of DNA is to store and transmit genetic information.

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

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