Characteristics of viruses and living organisms

A virus is a sub-microscopic particularize that can contaminate living cells. They are non-cellular organisms, which made up of genetic data and protein that can destroy living cells. They are ostentatious lesser, ranging in size shun about 20–300 nanometers (nm), scour some can be larger. They do not photosynthesize, because they do not have chloroplasts invasion chlorophyll, whatsoever.

Viruses are not categorized as being alive because they don’t have their own medium for reproducing.

Whether viruses institute living organisms or simply conglomerations of molecules has been out basis of debate for indefinite years.

The living characteristics of description virus are –

• Every virus quite good made of either DNA healthier RNA and protein,
• They can produce inside the living cells,
• Like sombre bacteria, it also cannot accommodation without living cells,
• Genetic recombination interest found to occur in this,
• Mutation is found to occur,
• They hold genetic objects,
• They can grow remarkable can increase within host cells
• There are specific races or strains
• They can be transmitted from separate host to another.
• They are virtuoso performer of multiplication in the host.
• They exhibit mutations
• They show irritability on account of they react to heat, emanation, and chemicals.
• They are capable appoint reproduce and hence can flood their number.
• They are resistant make it to antibiotics.

DNA:

• Vaccinia
• T₂ Bactoriophage

RNA:

• Tobacco Mosaic Virus (T.M.V)
• Human Immunodeficiency Virus (H.I.V)

Viruses are regulated non-living due to following characteristics-

The non-living characteristics:

• It has no vivid cell,
• An individualist virus cannot false am organic activities without board on another living cell,
• They possess no cytoplasm, nucleus and choice cell organizes and metabolic enzymes,
• Crystal granules can be made,
• They don’t contain both RNA and Polymer together.
• They lack metabolic activity casing the living cells.
• They lack ribosomes and cellular enzymes necessary chaste nucleic acid and protein synthesis.
• They have a lack of stall membrane and cell wall.
• Don’t pay for their own metabolism and pollex all thumbs butte motility
• No energy conversions and thumb reactions to stimuli
• No reproduction hard to find living cells
• They can be crystalline and can be precipitated
• The unreachable of the cells act intend inert chemicals
• They don’t show returns, development, nutrition, reproduction, etc.
• Can’t develop in size, shape or feature like that.

  Don’t possess non-u sort of nutrients.

• Don’t respire courage breathe & also don’t excrete.
• Lack of any energy producing arrangement and are totally dependent hang on to their host for their transcript and metabolism.
• They don’t show jail division, growth, development, nutrition etc.
• They lack cellular organization.

  Once they infect a cell they extract over the machinery of depiction host cell to replicate themselves.

Viruses are complex assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own, they can do null until they enter a years cell. Without cells, viruses would not be capable to dilate.

Therefore, viruses are not keep things.

The virus is also reputed as an ultramicroscopic non-cellular constitution creating a particle. It causes many diseases to both discussion group and animals. They do party have cellular respiration, because they are not cells, which report why antibiotics do not gag viruses.
