What is a nucleotide?

Back

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

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What is the base pairing rule in DNA?

Back

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

Front

What is the structure of DNA?

Back

DNA has a double helix structure, resembling a twisted ladder, with two strands running in opposite directions.

Front

What role does deoxyribose sugar play in DNA?

Back

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

Front

What is a gene?

Back

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

Front

What is the function of DNA?

Back

The primary function of DNA is to store and transmit genetic information that guides the development and functioning of living organisms.

Front

How do mutations affect DNA?

Back

Mutations are changes in the DNA sequence that can lead to variations in traits, and they can be beneficial, harmful, or neutral.

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.
