Why is it necessary for the genetic material in a cell to exist in chromatin form during normal cellular activity, and not in chromosome form?

Answer/ Explanation:

Chromosomes are highly condensed and compact structures. This means the chromatin (protein plus DNA complex) is hierarchically organised into tight structures through progressive folding of chromatin.

However, this is only the case during cell division. When the cell is in interphase and performing its normal duties, it is in a much more decondensed structure. This is because in order for transcription to occur, the cell needs to be able to access the information in the DNA. For example, transcription factors need to bind at their gene promoters to promote transcription.

When the DNA is folded into chromosomes, cellular factors do not have access to the genetic information due to the physical constraints of the chromatin structure.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
