Question 1
In a mammalian female, Xist upregulation on the active X chromosome is prevented by:
◦ targeted degradation by a protein complex.
◦ histone modification.
◦ a protein repressing expression of the
Xist gene.
◦ an antisense RNA.
◦ a protein preventing propagation of
Xist.
Question 2
In eukaryotes, methylation of DNA is associated with:
◦ activation of DNA replication.
◦ repression of DNA replication.
◦ gene activation.
◦ gene inactivation.
◦ suppression of translation.
