Answer:
The correct answer is - Histones are positively charged.
Explanation:
Histone is an octamer that is made up of four proteins and each protein has 2 copies. These proteins are H2A, H2B, H3, and H4. Histone proteins are mainly made up of positively charged amino acids like arginine and lysine which gives histone proteins an overall positive charge.
This positive charge of histone plays important role in the binding of DNA around it because phosphate group present in the DNA makes DNA negatively charged molecules that are attracted by positively charged histone protein by electrostatic interaction.
This interaction results in the wrapping of DNA around the histone proteins and then compaction of DNA into chromatin. Therefore the right answer is- histones are positively charged.
A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. Compare with mitosis.

The answer is radial symmetry.
Radially symmetric organisms have no left or right side of the body. Their body can be divided into equal parts about a central point. It is like cutting a pie into equal parts. The body parts are extended outward from its center. This type of symmetry is characteristic for<span> starfish, urchins, sea cucumbers, sea anemone, jellyfish, corals.</span>
