Prokaryotic cells lack organelles and have free-floating DNA and RNA. Prokaryotic transcription is controlled by RNA polymerase, which initiates transcription at the promoter site and creates unusable transcripts before continuing. The strength of the binding between RNA polymerase and DNA is related to the consensus sequence. Transcription occurs at about 40 nucleotides per second and […]
Prokaryotes and eukaryotes have different cell structures and ways of making cells work. Prokaryotic ribosomes are composed of 50S and 30S subunits, containing RNA and protein molecules. Ribosomes attach to mRNA and transfer RNAs to form proteins. Prokaryotic ribosomes are fast and can string together up to 20 amino acids per second. Scientists divide cellular […]
