Hi I'm having a little bit of trouble with this concept could someone see if my notes are sufficient?
Starts at Nucleus
transcription, = where the coded information for the construction of the protein is copied from a DNA template strand into mRNA (messenger RNA):
rRNA travels into cytoplasm at atttaches to ribosomes (free or on ER)
translation= where the mRNA codons are decoded into a polypeptide chain consisting of a specific sequence of amino acids using complementary tRNA (in lots on 3 for a codon)
Transporting and processing – endoplasmic reticulum
Proteins synthesized by RER are further modified in Golgi apparatus and then packaged in vesicles for export from cell
Transporting and processing – endoplasmic reticulum (extensive network of interconnected membranous sacs and tubules branching throughout cell and can be smooth or rough)
Endoplasmic reticulum – extensive network of interconnected membranous sacs and tubules branching throughout cell and can be smooth or rough
Proteins synthesized by RER are further modified in Golgi apparatus and then packaged in vesicles for export from cell
Packaging – Golgi apparatus (stack of cisternae and matrix that encompasses it)
They are exported by the Vesicles in exocytosis.
