Question

describe the main characteristics in virus in berif​

Answer 1

Answer:

• The various characteristics of viruses are:
• They are smaller and simpler than bacteria.
• They are ultramicroscopic and visible only under an electron microscope.
• They are considered to be on the boundary line of living and non-living things.
• They are obligate parasites and cannot live on their own.

Answer 2

Answer:

Viruses are infectious agents with both living and nonliving characteristics.

Living characteristics of viruses include the ability to reproduce – but only in living host cells – and the ability to mutate.

Nonliving characteristics include the fact that they are not cells, have no cytoplasm or cellular organelles, and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery.

Viruses can infect animals, plants, and even other microorganisms.

Since viruses lack metabolic machinery of their own and are totally dependent on their host cell for replication, they cannot be grown in synthetic culture media.
