Answer:
f. Methylation of the DNA is maintained because methylation enzymes act at DNA sites where one strand is already methylated and thus correctly methylated daughter strands after replication.
Explanation:
DNA methylation is the addition of methyl group to DNA.it is an example of EPIGENTICS mechanism in genetics( epigentic refers to modification of expression of genes instead of altering the gene codes),
The objective of this mechanism is to modify the function of the particular GENE, therefore affecting the expression of the gene,
This phase is metaphase, and you can remember this by seeing the m means middle.
The chromosomal combination allows for each sex cell that is going to be produced to have different DNA combinations, allowing for the offspring to be not only different from the parents, but also allows for genetic diversity.
