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.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
