Gaucher disease type 1 (GD1 ) is a recessive genetic disease that affects 1 in 900 individuals in a particular population. GD1 is caused by a mutation in the enzyme glucocerebrosidase. Assuming the population is in Hardy-Weinberg equilibrium, calculate the frequency of the wild-type (nonmutant) allele for the enzyme glucocerebrosidase.

Using the Hardy-Weinberg equilibrium equation, the frequency for the wild-type allele (referred to as p, see explanation below) comes out to be

Explanation:

An individual will have to be homozygous recessive for the mutation in the enzyme glucocerebrosidase to have the Gaucher disease type 1 (GD1). This percentage will be

= × 100 =

= =

We know that because the sum of both allele frequencies has to be 100%

So

Hence,

Hope that answers the question, have a great day!

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
