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 complementary base pairing in DNA?

Back

Complementary base pairing refers to the specific pairing of nitrogenous bases in DNA: Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

Where does DNA replication occur?

Back

DNA replication occurs in the nucleus of eukaryotic cells.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is transcription?

Back

Transcription is the process of synthesizing RNA from a DNA template, resulting in the formation of mRNA.

Front

What is translation?

Back

Translation is the process by which ribosomes synthesize proteins using the information carried by mRNA.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or stop signal during protein synthesis.

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) transports amino acids to the ribosome during protein synthesis and matches them to the coded mRNA message.

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.
