Why does each side of the DNA helix run opposite directions?
What do I need to know about RNA
mRNA – Messenger RNA is a messenger copy of DNA that is taken to the ribosomes
tRNA – Transfer RNA brings amino acids to a grove in the ribosomes where they can be linked together to form proteins
rRNA – Ribosomal RNA works with enzymes to speed up the assembly of amino acids into peptide chains
Making amino acids
Protein functional diversity
PROTEINS
FIBROUS PROTEINS
(structural)
GLOBULAR PROTEINS
(functional)
Insoluble, provide support and shape to
the cell and are components in
structural features such as membranes
Soluble
Catalytic proteins – ie enzymesMotility Proteins – ie flagella
Regulatory proteins – membrane receptors
