Bio1 - Transcription and Translation

What direction is the coding strand in?

5’ to 3’

What direction is the template strand in?

3’ to 5’

Is the template or coding strand read by RNA polymerase?

The template strand is read and copied by RNA polymerase, but the coding strand is identical to the RNA copy

What is the promoter site?

The point on the DNA that RNA starts being copied from

What does the initiation complex do?

It starts transcription

What direction does RNA polymerase move in and synthesize RNA in?

It moves in the 3’ to 5’ direction

It synthesizes in the 5’ to 3’ direction

What does mRNA do?

It carries information from DNA to the ribosome and acts as a blueprint

What does tRNA do?

It carries the correct amino acid to a peptide chain

What does rRNA do?

It makes up the ribosome

What is the start codon?

AUG

What are the stop codons?

UAA UAG UGA

What is the release factor?

A protein that binds to the stop codon, stopping protein synthesis.

What is the order of the tRNA binding sites?

APE
