Nucleus is the main component of the cell and carries out the vital processes of the cell.

  • For learning about its structure, a nucleus diagram is quite helpful. Important components of its structure include.
  • One feature of the nucleus that distinguishes eukaryotic cells from prokaryotic ones is the nuclear membrane.
  • Additionally, it has a double-layer structure. It also has phospholipids in it.
  • The nuclear envelope, nucleoplasm, or nucleus sap, nuclear matrix, chromatin, and nucleolus are some of the several structures that make up the nucleus.
  • The nuclear membrane, also referred to as the nuclear envelope, creates an envelope-like structure surrounding the nuclear contents.

storchak [24]
It should be 18 because:
100 x 2 = 200
200 + 70 = 270
360 - 270 = 90
90/5 = 18
So x = 18

The enzymes that are used to replicate a virus are synthesized by ______.
Vladimir79 [104]

The enzymes that are used to replicate a virus are synthesized by the host cell. That is option A.

<h3>Process of viral infection.</h3>

A virus is a microorganism that has the ability to reproduce only by infecting a living host.

The main features of a virus include:

  • capsid

  • nucleic acid genome ( RNA or DNA)

  • Envelope membrane

For a virus to be able to cause an infection,it has to pass through the following steps:

  • Attachment of the virus to the host cell.

  • Entry of the viral genetic material into the host cell

  • Genome replication and gene expression: through the ribosomes of the host cells, enzymes are released which are used to replicate the invading virus to produce new ones.

Therefore, the enzymes that are used to replicate a virus are synthesized by the host cell.
