Proteins Flashcards
How do amino acids link up?
Condensation reactions
What is an oncogene?
A normal cellular gene which has been altered in a way that allows it to participate in oncogenesis - the formation of cancer
Where must alterations occur for a gene to become an oncogene?
at the level of the genome
What alteration cause changes to the genome
Insertion deletion translocation inversion
Name the 4 different structures of a protein
Primary,secondary, tertiary and quarternary
Decribe the primary structure
The amino acid sequence
Describe the secondary sequence
The amino acids fold forming the secondary structure. Contains beta sheets and alpha helixes
Describe the tertiary structure
Protein folding into its final shape
Describe the quarternary structure
The coming together of protein sub units
