Compare and contrast point mutations and frame shift mutations

Point mutation:

In point mutation, one nucleotide is swiped for another.

Frame shift mutation:

Frame shift mutation are due to either insertion or deletion of nucleotide. This causes the entire DNA to elongate or shrink in size.

Frame shift mutation may alter all the codons that occur after insertion or deletion.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
