Transcription and Translation

Front

What is transcription?

Back

Transcription is the process by which the genetic information in DNA is copied into messenger RNA (mRNA). It occurs in the nucleus of the cell.

Front

What is translation?

Back

Translation is the process by which the sequence of nucleotides in mRNA is used to synthesize proteins. It occurs in the ribosome.

Front

Where does transcription take place?

Back

Transcription takes place in the nucleus.

Front

Where does translation take place?

Back

Translation takes place in the cytoplasm, specifically at the ribosome.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA 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, where it is translated into a protein.

Front

What is the start codon?

Back

The start codon is AUG, which signals the beginning of translation and codes for the amino acid Methionine.

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in DNA and RNA is translated into the amino acid sequence of proteins.

Front

What is an amino acid?

Back

An amino acid is a building block of proteins. There are 20 different amino acids that combine in various sequences to form proteins.

Front

What is the function of ribosomes?

Back

Ribosomes are the cellular structures where translation occurs, synthesizing proteins by linking amino acids together.
