Question

Give atleast 10 characteristics of Virusses___!!

Answer 1

The study virus is known as virology.

▪︎Viruses belong to intermediates on between living and nonliving worlds.

▪︎Their size varies from 10-250 nm.

▪︎Viruses have any extremely basic structure made up of a central core of either DNA or RNA strands.

▪︎This is covered by a protein coat called capsid.

▪︎The viruses don't have any cytoplasm or other metabolic machinery.

▪︎They depend entirely on metabolic enzymes of the host cell.

▪︎Inside the living cells of the viruses behave as living structure as they multiply and grow.

▪︎Once outside the organisms virus behave as non living entities.

▪︎Viruses infective variety of organisms including blue green algae.

▪︎Viruses in fact almost every kind of prokaryotic and Eukaryotic cells.

▪︎Some examples are Rhinovirus , HIV.

Answer 2

$\huge\underline\mathfrak\purple{Answer}$

the 10 characteristics of viruses are →

⭕they are submicroscopic and non cellular . They are considered neither prokaryotes or eukaryotes .

⭕They are smaller than 200 nm (even smaller than bacteria )

⭕they are obligate parasites .

⭕they have genetic material either in the form of RNA or DNA .

⭕when outside their specific host , they are present in crystalline form .

⭕they are intracellular parasites ,i.e., they affect a cells of host .

⭕For protein synthesis they take help of host cell's ribosomes .

⭕they may spherical , rod shaped or tadpole like .

⭕generally plant viruses have ssRNA and animal viruses have double stranded DNA .

⭕They have a protein coat called capsid and its each subunit is called as capsomere .
