Question

33. (1) Most imprinted genes are silenced. What is one exception to this rule?


H19

Igf-2

UBE3A

SNRPN

Answer 1

this is knowledge you don't normally need. don't you have a reader or some special book where you can find answers to those questions?

aaanywho. I spent my time on wikipedia and can tell you: all of these genes underlie the mechanics of imprinting and are therefore silenced. The only exception I found is UBE3A, which is expressed by both alleles in most tissues, while in the brain, only one allel will express the protein.

but, again, this is so specialized, that you may forget it after your exam. .-)
