Transcription and Translation Flashcards
What is transcription ?
The process of making an mRNA copy of a gene from DNA in the nucleus
What enzyme is essential for transcription ?
RNA polymerase
Where does translation occur in the cell ?
In the ribosomes in the cytoplasm
What is the role of tRNA in translation ?
To bring the correct amino acid to the ribosome according to the mRNA codon
What is the role of tRNA in translation ?
To bring the correct amino acid to the ribosome according to the mRNA codon
What are the base pairing rules for mRNA transcription ?
A pairs with U C pairs with G
What is a codon ?
A three base sequence on mRNA that codes for a specific amino acid
What is the final product of translation
A polypeptide chain that folds into a functional protein
What is translation ?
The process where the sequence of mRNA is used to assemble amino acids into a polypeptide (protein) at the ribosome
