Answer:
by mutation of genes encoding histone modification enzymes that lead to loss of gene repression by the alteration of the chromatin structure
Explanation:
Histone methylation is an important epigenetic modification involved in regulation of gene expression. Histone methyltransferases and histone demethylases are enzymes capable of modifying the chromatin structure by adding or removing methyl groups of the N-terminal of the core histones, respectively. There are suppressor of variegation (Su-var) enzymes capable of removing activating chromatin marks such as, for example, histone H3 lysine methylation, thereby mutations in these epigenetic modifiers may result in a loss of gene silencing by directly opening the chromatin structure. For example, Su(var)3–9 is a histone lysine methyltransferase enzyme that controls the formation of heterochromatin.

Answer:
281474976710656
Explanation:
As each half hour passes, the colony of bacteria doubles. Initially, the numbers are fairly low, but the amounts become larger and larger as they compound.
Hour 0- 1
Hour 0.5- 2
Hour 1- 4
Hour 1.5- 8
Hour 2- 16
Hour 2.5- 32
By hour 10, the bacteria will have increased to 1048576. By hour 15, the number of bacteria will be 1073741824. By hour 24, the colony will contain 281474976710656 bacteria.
