which are the three main criteria used in classifying viruses?

Scientists use three key characteristics to classify the similarities and differences of chromosomes. These three key features are size, banding pattern and centromere position.

Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs (rRNA), the cell's membrane lipid structure, and its sensitivity to antibiotics. The three domains are the Archaea, the Bacteria, and the Eukarya.

['Nucleic acid -contains 3-400 genes. ... ', 'Capsid -The capsid accounts for most of the virion mass. ... ', 'Envelope -this is an amorphous structure composed of lipid, protein and carbohydrate which lies to the outside of the capsid. ... ', 'Spikes. ... ', 'Icosahedral -The protomeres aggregate in groups of five or six to form the capsomere.']

Viruses are therefore classified as either DNA or RNA viruses. The hepatitis C virus (HCV) is a RNA virus. In a DNA virus there are two complementary and intertwined strands of nucleic acid (the double helix).

State which characteristics or properties viruses have in common with living organisms. The characteristics that viruses have common with living organisms are reproduction and heredity. They can only reproduce inside the host cell and they do have DNA or RNA.

Classification of Viruses. Morphology: Viruses are grouped on the basis of size and shape, chemical composition and structure of the genome, and mode of replication. Helical morphology is seen in nucleocapsids of many filamentous and pleomorphic viruses.

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

Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs (rRNA), the cell's membrane lipid structure, and its sensitivity to antibiotics. 3. The three domains are the Archaea, the Bacteria, and the Eukarya. 4.

Whittaker proposed an elaborate five kingdom classification – Monera, Protista, Fungi, Plantae and Animalia. The main criteria of the five kingdom classification were cell structure, body organisation, mode of nutrition and reproduction, and phylogenetic relationships.

The nucleic acid is usually double-stranded DNA (dsDNA) but may also be single-stranded DNA (ssDNA). DNA viruses belong to either Group I or Group II of the Baltimore classification system for viruses. Single-stranded DNA is usually expanded to double-stranded in infected cells.
