You are working in a laboratory that is studying a newly isolated virus. your job is to culture the virus using in vitro methods. upon observing your inoculated tissue culture specimen one day, you notice clumps of cells growing on top of the original monolayer of cells. microscopic analysis of stained cells from the culture reveal an alteration in host cell membrane protein content and chromosomal structure. based upon this information, you hypothesize that the virus you are studying is

Oncovirus  is the virus that is studied

Explanation:

Oncovirus are the tumour causing viruses, which has been a dominant in causing leukaemia and also solid tumours in lower species. Oncovirus grows clumps of cells in the upper layer of the original cell. Transformation of cells as well as the tumour formation in experimental cells are induced by the oncoviruses. viruses remain unique form one another because of their nucleic acid, morphology, mode of replication, host range and type of antigens induced in the tumour or induced cell.

yes, because even though a theory has a  lot of evidence to support it, it is not always true
