"The following are genotypes of merozygotes of E. coli with various combinations of lac operon mutations. Determine the phenotype with respect to beta-galactosidase (z), permease (y), and deacetylase (a) of each combination as U = uninducible, I = inducible, and C = constitutive. i- p+ o+ z+ y+ a-/i+ p+ oc z- y+ a+ "

Explanation:

As given;

Z translated into  beta-galactosidase;

y into permease;

And A into deacetylase;

and

U= uninducible,

I= inducible;

C= contitutive,

and  p= promoter, o= operator,  and etc

as here

merozygote  i- p+ o+ z+ y+ a-/i+ p+ oc z- y+ a+

it will constitutively encode for y+ and a+;  as the o⁽ is constitutive of i+ p+ oc z- y+ a+

and there is no synthesis from i- p+ o+ z+ y+ a- because  of i+ of i+ p+ oc z- y+ a+

z -

y +

a +

So it will constitutively encode permease (y), and deacetylase (a)

and there is no production of beta-galactosidase (z).

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

is this for the e2020 class
