Structure of DNA

Front

What is DNA?

Back

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

Front

What are the four bases of DNA?

Back

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

Front

What is the structure of DNA?

Back

DNA has a double helix structure, resembling a twisted ladder.

Front

What is base pairing in DNA?

Back

Base pairing is the specific pairing of nitrogenous bases: Adenine pairs with Thymine, and Guanine pairs with Cytosine.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is a gene?

Back

A gene is a section or piece of DNA that contains the instructions for making a specific protein.

Front

What is the role of DNA in cells?

Back

DNA stores and transmits genetic information that guides the development and functioning of living organisms.

Front

What is replication in DNA?

Back

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

Front

What is the function of the sugar-phosphate backbone in DNA?

Back

The sugar-phosphate backbone provides structural support and stability to the DNA molecule.

Front

What is the significance of the order of bases in DNA?

Back

The order of bases in DNA determines the genetic code, which dictates the traits and functions of an organism.
