Synthesis of Proteins Notes
Transfer RNA (tRNA)- molecule which transfers amino acids from the
cytoplasm to ribosome.
Cytoplasm is stocked with all 20 amino acids, gained by synthesizing them
from other compounds or taking them up from surrounding s
Prokaryotes (Bacteria) Vs. Eukaryotes Notes
Contain different RNA polymerases; eukaryotes depend on transcription
Transcription is terminated differently
Slightly different ribosomes
Promoter- the region of DNA where RNA polymerase attaches and initiates
RNA Polymerase- enzyme that pries DNA strands apart and hooks
together RNA nucleotides with base pairing along DNA template
Protein Pumps Notes
