What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life. It is composed of two strands that coil around each other to form a double helix.

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 base pairing rule in DNA?

Back

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

What is the shape of a DNA molecule?

Back

A DNA molecule has a double helix shape.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What is the role of RNA in protein synthesis?

Back

RNA serves as a messenger that carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

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 the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized by translating messenger RNA (mRNA).

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.
