Which of these, according to the Baltimore system of virus classification, is incorrect Select one:1. Class I: SSDNA 2. Class III: dsRNA 3. Class IV: (+)SSRNA 4. Class V: (-)SSRNA 5. None of the above

Question

Viruses morphology and ultrastructure.  Cell cultures in virology.Serologic reactions used in virology. 

Answer 1

The Baltimore Classification System is a scheme for classifying viruses based on the type of genome and its replication strategy. The system was developed by David Baltimore.

The seven classes of viruses in the Baltimore classification system are as follows:

1. Class-I : dsDNA viruses
2. Class-II : ssDNA viruses
3. Class-III : dsRNA viruses
4. Class-IV : (+) sense ssRNA viruses
5. Class-V : (-) sense ssRNA viruses
6. Class- VI : (+)sense ssRNA reverse transcriptase viruses
7. Class-VII : dsDNA reverse transcriptase viruses.

Based on the options given in the above question the answer will be option # 5, because all the other options mentioned belong to their original class.

Hope this helps.

Thank you.
