Hello.
I am reading a book that deals with virus evolution.
In hypotheses on the origin of viruses, there is a sentence
" Viruses are derived from degenerate cells that eventually parasitised normal cells"
what is degenerate cell???
s. Béatrice Marianne Ewalds-Kvist
Nonlethal injury to a cell may produce cell degeneration, which is manifested as some abnormality of biochemical function, a recognizable structural change, or a combined biochemical and structural abnormality. Degeneration is reversible but may progress to necrosis if injury persists. When it is associated with abnormal cell function, cell degeneration may also cause clinical disease.
