1. Viruses are a cellular, non-cytoplasmic infectious agents.
2. They are smaller than bacteria, and this can pass through bacteriological filter.
3. Viruses are transmissible from disease to healthy organisms.
4.All viruses are obligate parasites and can multiply only within the living host cells.
5.Viruses contain only a single type of nucleic acid either DNA or RNA.
6. Viruses are host specific that they infect only a single species and definite cells of the host organisms.
7. Viruses are effective in very small doses. They are highly resistant to germicides and extremes of physical conditions.

∙ 13y agoA virus is non-cellular with a typical size of 20-30 nanometers. They contain no cytoplasm or organelles. They have no chromosomes only, RNA and DNA. They have a protein coat. They depend on cells from a host plant or animal for metabolism and reproduction since they are not living organisms.

Viruses show extremely specific intracellular parasitism.
They can easily be crystallized and precipitated.
Viruses have no cytoplasm,nucleus,membranes,ribosomes,enzymes etc.

What is true viruses?
Viruses are cellular parasites.
Does heredity occur in viruses-?
Heredity does occur in viruses. When a virus replicates it carried it to the offspring.
How do you explain how copies of viruses are produced?
copies of viruses are produced because some viruses stay inside there host cells.
How are viruses spread from cell to cell?
New viruses are released after the lytic cycle. ~Gradpoint/Novanet
Which is easier to cure viruses or bacteria?
actually, curing bacteria is easier than viruses because they can be treated by antibiotics while viruses cant and its result of viruses don't have stable and similar morph
Which features suggests that viruses are non-living microbes?
They replicate using a host cell's metabolic machinery.
What the features of Clam Antivirus?
Clam Antivirus features fast scanning and is equipped to detect over 1 million viruses, worms, and trojans. It also features support for most mail file formats and HTML.
What is the best desktop camera?
Mac 1 They are super fast 2 Great programs and features 3 They are less likely to get viruses
How do you protect your data from viruses?
You intall an anti-virus software. The cheaper you go, the less features there are and of course, the most you pay, the better features and protection there is. If you are going for a free one, I don't recommend AVG.
Name two features that distinguish viruses from bacteria?
All bacteria use their own ribosomes for protein synthesis while all viruses have to use their hosts' ribosomes. All bacteria have their own energy generation mechanisms (cellular respiration or photosynthesis) while all viruses have no intrinsic energy generation mechanisms.
What computer program is used to prevent computer viruses from infecting a computer?
Many programs today have security features built-in which are designed to stop viruses from infecting your computer. The main program that does this though is called an anti-virus program. This type of program removes viruses from your computer and sometimes attempts to stop viruses from being installed or even downloaded. There are many free programs of this type, such as AVG or Microsoft Security Essentials.
Are there any benefits associated with using apache openoffice verses Microsoft office?

What are the main features of the Honeywell 50250 air purifier?
There are many features of the Honeywell 50250 air purifier. Some of the features of the Honeywell 50250 air purifier include removing 99.97 percent of common airborne pollutants, removing airborne particles, viruses, and materials, and a reminder telling you when to replace the filter.
What features are found in both cells and viruses?
Not all cells have organelles; only eukaryotic cells do. Viruses, likewise, are not eukaryotic cells and thus, have no organelles. Viruses are generally very small particles many orders of magnitude smaller than the smallest cell. In short, viruses have no organelles, so your question is nonsensical.
What lifelike features do viruses have?
Viruses have features including genes made from either DNa or RNA, protein coats that protect these genes, and some have a layer of fat surrounding them when they are outside a cell for insulation and protection. Retroviruses have the unique ability to change the host's RNA into mutant DNA.
What are the 3 types viruses?
Computer viruses, Macro Viruses, and Directory Viruses
Virology is the study of what?
