How many additional capsomeres are found in an adenovirus, as compared to those in a herpes virus?
Correct answer: C. 90
- A. 70
- B. 80
- C. 90
- D. 100
Explanation
Adenoviruses and herpesviruses are both icosahedral viruses, but they differ in the number of capsomeres present in their capsids. An adenovirus has a total of 252 capsomeres, consisting of 240 hexons and 12 pentons. In contrast, a herpesvirus capsid is composed of 162 capsomeres, made up of 150 hexons and 12 pentons. This means that adenoviruses possess 90 additional capsomeres compared to herpesviruses, which contributes to their structural differences despite both sharing icosahedral symmetry.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
