Which of the following is true regarding cultivation and isolation of animal viruses? View Available Hint(s) Which of the follow

ing is true regarding cultivation and isolation of animal viruses? Mouse models are available for virtually all human viral infections and can be routinely used for vaccine development. The preferred and widely used method of viral isolation and growth is via growth in an embryonated egg. Viruses can be easily grown in liquid culture without any other organisms present. Diploid cell culture lines, developed from human embryos, are widely used for cult

.....culturing viruses that requires a human host

Answer:

Diploid cell culture lines, developed from human embryos, are widely used for culturing viruses that require a human host

Explanation

Viruses can not thrive in a non-living host or artificial media.They  are intracelular parasites  which needed living host to replicate . Cultures lines from Human embryo  in are therefore used for culturing viruses of human host, so that its mode of replication and gene expression can be studied, and therefore its virulence can easily be studied.

This method have the advantage that;

1.there is no need to make use of the whole animal rather,on a tiny tissue needed can be isolated for culture.

2. the cells growth is continuous,and can be preserved in liquid Nitrogen and renew for future culture

3. cells can be grown in different containers,  with ability to decide the number of cells needed.

Temperature is kept at optimum for human in the culture at  37 degree centigrade, nutrients are provided, NaHC03 as buffers for C02, and  the medium is humidified.

Long before the structure of DNA was solved, the physicist Erwin Schrodinger suggested that the three-dimensional arrangement in
Georgia [21]

Watson and Crick's model explained mutability because bases pairs can suffer changes (mutations) during DNA replication. Moreover, this model also explained stability because DNA strands are held together by hydrogen bonds.

Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.

In Watson and Crick's model, both DNA strands are held together by hydrogen bonds between nitrogenous bases on opposite DNA strands, thereby providing stability to the DNA molecule.

In DNA, Guanine always pairs with Cytosine by three hydrogen bonds, while Adenine always pairs with Thymine by two hydrogen bonds.

Moreover, Watson and Crick suggested that mutations could occur as a consequence of a base occurring very infrequently in one of the less likely tautomeric forms during DNA replication, thereby also explaining the mutability of life.
