DNA/RNA Structure

Front

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 is RNA?

Back

RNA (Ribonucleic Acid) is a single-stranded molecule that plays a crucial role in the synthesis of proteins. It is involved in translating the genetic information from DNA.

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 are the four nitrogenous bases in RNA?

Back

The four nitrogenous bases in RNA are Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).

Front

What is a nucleotide?

Back

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

Front

What is base pairing in DNA?

Back

Base pairing in DNA refers to the specific pairing of nitrogenous bases: Adenine pairs with Thymine, and Cytosine pairs with Guanine.

Front

What is the role of thymine in DNA?

Back

Thymine is one of the four nitrogenous bases in DNA and pairs with Adenine during DNA replication.

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a DNA molecule makes a copy of itself, ensuring that each new cell receives an identical set of genetic information.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.

Front

What is transcription?

Back

Transcription is the process by which the information in a DNA sequence is copied into a complementary RNA sequence.
