The viral genome, incorporated and integrated with the bacterial genome, is referred to as
Correct answer: A. Prophages
- A. Prophages
- B. DNA
- C. RNA
- D. Both A and B
Explanation
The viral genome, when incorporated and integrated into the bacterial genome, is referred to as a prophage. This occurs during the lysogenic cycle of certain bacteriophages, where the phage DNA becomes stably integrated into the host bacterium's chromosome instead of immediately directing viral replication. In this dormant state, the viral genome is replicated along with the bacterial DNA and passed on to daughter cells during cell division. The prophage may remain inactive for many generations, but under certain stress conditions, it can be induced to enter the lytic cycle, leading to the production of new phage particles and eventual lysis of the bacterial cell.

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.
