The amount of enzyme activity in a cell that is homozygous for a mutant allele is 0 units. The amount of enzyme activity in a cell homozygous for the WT allele is 200 units. The amount of enzyme activity in a heterozygote is 0 units. What type of allele is the mutant allele?
a. null/amorphic
b. neomorphic
c. dominant negative
d. hypomorphic
e. hypermorphic

The best answer is "C"

Dominant negative

Explanation:

Dominant negative represents a class of mutation in which a mutant receptor interferes with the function of the wild-type version of the receptor.

null/amorphic: It is a form of mutation that causes the complete loss of Gene function (protein) by disrupting translation and/or preventing transcription.

Neomorphic: Describes a mutation where altered gene product possesses a completely new molecular function and sometimes pattern of gene expression.

Hypmorphic: describes a mutation that causes a partial loss of gene function usually through reduced (protein, RNA) expression or reduced functional performance.

hypermorphic: describes a mutation that causes an increase in the normal gene function resulting from increased mRNA or protein expression.

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
