Sequence mRNA specifies
amino acid sequence
in polypeptide according
to a code.
Ribosome assembles the
amino acid sequence NOTE THE KEY DIFFERENCES! 11 Fig. 13-3, p. 287 Prokaryote occur in one compartment, eukaryote in
different compartments. It will be processed in the
nucleus, transported and then translated. How they
get from one place to another is regulated. Since
transcription and translation occur in the same
compartment, they can be coupled. So you can be
translating while its being transcribed. Transcription is
going 5' to 3', when the 5' end is released thats got the
condos that code for amino terminal so we can bind
ribosomes and start translating. They cannot be in the
eukaryote unless you are in an organelle b/c both
processes occur in the same compartment.
