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.
Option (E) is the characteristic of some viruses as some have envelopes, but many do not.
Viruses are characterized as microscopic particles that can integrate their genetic material into a host. Numerous viruses have the potential to harm the host cells.
A virus's structure consists of DNA or RNA that is encased in an envelope-like or capsid-like structure. Proteins make compose the capsid or envelope. Additionally, some viruses have a tail.
A virus often injects its viral genome into the host cell while its capsid stays outside the host cell. The virus' DNA or RNA subsequently fuses with the host cell.
