What is DNA?

Back

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

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 RNA?

Back

RNA (Ribonucleic Acid) is a single-stranded molecule that plays a crucial role in the synthesis of proteins. It is made up of nucleotides, which include the bases Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).

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. Mutations can be caused by errors during DNA replication or by environmental factors.

What is the complementary base pairing in DNA?

Back

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

Front

What is the role of proteins in the body?

Back

Proteins are large molecules made up of amino acids that help repair and build tissues, act as enzymes, and perform various functions in the body.

What is mRNA?

Back

mRNA (messenger RNA) is a type of RNA that carries genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the function of enzymes?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in the body, including the process of DNA replication.

Front

How does DNA replication occur?

Back

During DNA replication, the double helix unwinds, and each strand serves as a template for the formation of a new complementary strand.

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains the sugar deoxyribose, while RNA is single-stranded and contains the sugar ribose.
