The following are a list of regulatory sites that are partly identified by looking at sequences. Which of them are found in RNA as well as DNA? A. Promoter B. Operator C. Ribosome binding site D. Start codon

Question

anonymous · Answer

A ribosomal binding site (RBS) is a sequence on mRNA

Promoter - a short sequence of DNA where RNA polymerase first attaches when a gene is to be transcribed. 

Operator - a short sequence of DNA where the repressor binds, preventing RNA polymerase from attaching to the promoter.

The start codon is the first codon of an mRNA transcript translated by a ribosome.
