What is the Central Dogma of Molecular Biology?

Back

The Central Dogma describes the flow of genetic information from DNA to RNA to protein.

What is transcription?

Back

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

Front

What is translation?

Back

Translation is the process of decoding RNA to synthesize proteins.

What are nucleotides?

Back

Nucleotides are the building blocks of nucleic acids, consisting of a sugar, phosphate group, and nitrogenous base.

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

What are the four nitrogenous bases in RNA?

Back

Adenine (A), Uracil (U), Cytosine (C), Guanine (G).

Front

How many nucleotides are needed to code for one amino acid?

Back

Three nucleotides are needed to code for one amino acid, forming a codon.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides that corresponds to a specific amino acid.

Front

What is the role of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the role of tRNA?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during translation.
