The pathogens travel through the blood and irritate cells. The irritation of cells can cause the body to consume more energy, to repair the damage. This causes symptoms like tiredness, regurgitation, and sometimes in extreme cases, death.
DNA replication is a process in which two copies of DNA which are duplicate of each other are formed from original one so <span> the event that will follow DNA replication in a cell cycle is
</span><span> Chromosome duplication
</span>because by this new genetic material is produced and it is also defined as duplication of the gene containing region of DNA
so i conclude option B is correct
hope it helps
