44
Q

is also known as the protein coat that encloses and protects the nucleic acids.

A

Capsid-

45
Q

are those found living inside their hosts. Though some of these spend a portion of their life in water or soil, their mature forms live within animal hosts and are often highly adapted to this specialized environment.

  • Polyhedral Viruses
48
Q

Like the infamous Coronavirus, are essentially helical viruses enclosed in a membrane known as an envelope, which is spiked with sugary proteins that assist in sticking to and entering host cells.

A
  • Spherical Viruses
49
Q

Like bacteriophages, which infect and kill bacteria, resemble a lunar lander and are composed of a polyherdal “head” and a helical body (or “soil sheath”) and legs ( or “tail fibers”) that attach to a cell membrane so that it can transfer its genetic material.

A
  • Complex Viruses
50
Q

are those found living outside their hosts. Many ectoparasites live on or near the organisms they require for nutrients, while some spend considerable time away from their hosts.

A
