How Does Position Effect Influence Gene Expression

Multiple Choice

How does position effect influence gene expression?

A) Point mutations in promoters frequently occur by this mechanism
B) Translocations may result in a promoter that is normally used for one gene now controlling an entirely different gene.
C) Since this mechanism relies on recombination it relies on the positioning of one allele so that it is under the control of the other allele.
D) Translocations always result in a gene being recombined into an area of heterochromatin.
