Transcription vs. Translation

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically messenger RNA (mRNA), which carries the genetic information from the nucleus to the ribosome.

Front

What is translation?

Back

Translation is the process by which ribosomes synthesize proteins using the information carried by mRNA. It involves decoding the mRNA sequence into a polypeptide chain.

Front

Where does transcription occur in the cell?

Back

Transcription occurs in the nucleus of the cell.

Front

Where does translation occur in the cell?

Back

Translation occurs in the cytoplasm, specifically at the ribosomes.

Front

What is mRNA?

Back

mRNA, or messenger RNA, is a type of RNA that carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is tRNA?

Back

tRNA, or transfer RNA, is a type of RNA that brings amino acids to the ribosome during translation, matching them to the codons on the mRNA.

Front

What is rRNA?

Back

rRNA, or ribosomal RNA, is a type of RNA that makes up the structural and functional components of ribosomes, facilitating the translation process.

Front

What is a codon?

Back

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

Front

What is the role of RNA polymerase?

Back

RNA polymerase is the enzyme that synthesizes mRNA from a DNA template during the transcription process.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of creating RNA from DNA, while translation is the process of synthesizing proteins from mRNA.
