Question

list the characters of virus





minimum 15 points

Answer 1

here's your answer


1)viruses are neither living or nonliving

2)viruses for this reason do not find a correct place in classification

3)viruses do not process cells hence they are not truly leaving

4)viruses are non cellular organisms

5)they are inert crystalline structure outside the living cell

6)once virus infected cell replicate themselves in the host cell and kill the host

7)virus contain both protein and genetic material either RNA or DNA

8)no viruses contain both RNA and DNA

9) a virus is nucleoprotein and it's genetic material is infectious

10)viruses that infect plants have single stand of RNA
11)the virus that infect animals have either single or double stranded RNA or double stranded DNA

12)viruses that infect bacterial cells are called bacteriophages which have Double stranded DNA

13)the protein coat of virus is called capsid made up of small units of capsomeres which protect the central nucleic acid

14)the capsid capsomers are arranging helical or polyhedral geometric forms

15)in plants tmv causes leaf mosaic disease, leaf curling disease ,leaf rolling disease, yellowing and vein clearing disease

16)viruses cause diseases in human being such as: AIDS , smallpox ,mums, herpes, influenza

▶ Characteristics of Virus are:-
============================⤵

[1] They are enclosed in a protective envelope.

[2] They have spikes, which helps them to attach to the host cell.

[3] They are non cellular.

[4] They do not respire, metabolize & grow but they do reproduce.

[5] They contain a protein coat called the capsid.

[6] They have a nucleic acid core containing DNA or RNA.

[7] Ribosomes and enzymes are absent, which are needed for metabolism.

[8] They are considered both as living & non living things.

[9] They make use of raw materials and enzymes of the host cell to reproduce & causes several infections.

[10] They are non-cellular organisms made up of genetic material & protein that can invade living cells.

[11] They are a strand of genetic material within a protective protein coat called a capsid.

[12] They infect a wide variety of organisms, including both eukaryotes & prokaryotes.

[13] They can replicate only by infecting a host cell.

[14] They cannot reproduce on their own.

[15] They are not cells.
