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,
As the flower takes water that it needs to survive, the dye in it has no more density so it goes up with the water dying everything in its path blue.
The electrons in the outermost shell of the covalent compounds are shared by nearby atoms. As there are no free electrons for conducting electricity, the covalent compounds are perfect insulators at absolute zero. As the temperature increases, some electrons move from valence band to conduction band. This gives rise to conductivity. But as the numbers of charge carriers are very low, covalent compounds are poor conductors. On the other hand metals are good conductors cause of their bonding. Metallic bonding consists of a sea of electrons rather than discreet bonds. The free electrons are able to move freely. Since electricity and heat need electrons to move, the bonding promotes conductivity.
