Chap 4 Class notes
Structure of protein and monomers → hierarchy
[HIGH YIELD]
the structure of a protein determines it's shape. → the shape of the protein
determines the function → this is typically relevant to enzymes and
denatruing which will be discussed later.
A protein funcitions at atleast 3 of the 4 structrual hierarchial levels.
primary ; specific arrangement of amino acids → present right after
translation when amino acids are being joined through condensation
polymerisation
Secondary ; the aplha helices or beta pleated sheeths → descirbes the
LOCAL folidng of the amino acids or protein
Tertiary → this typically accounts for the Active site of enzymes. It is the
GLOBAL coiling and folding of a protein to give it a 3D structure. → coiling
and folding is stablised by Hydrogen bonds and disulphide bridges.
Quaternary ; → whether or not the protein consits of multiple polypeptides
Transcription and Translation
[HIGH YILED]
Transcription
RNA polyemrase and other transcription factors bind to the promoter
region of the sequence
This sends signals, instructing the undiwing of the DNA helix, leaving the
nitrogneous bases exposed
