Sickle shaped red blood cells result from a mutation in the gene that codes for hemoglobin this mutation results in sickle cell anemia a partial sequence of bases from normal hemoglobin gene in a sequence that result in sickle cell anemia are shown below what type of mutation is depicted in the sequence

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
