A reverse reaction is the chemical reaction moving both forward and backwards.
An example of this is Ammonium chloride ⇌ ammonia + hydrogen chloride
This is a symbol for reverse reaction ⇌
The answer is; C
Plasmids are conferred through horizontal gene transfer in bacteria. The ‘male’ bacteria develops a structure called pili that then attaches to the ‘female’ bacteria. It then transfers it’s replicated plasmid to the ‘female’ bacteria in a process called conjugation. This bacteria will hence have desirable traits that are coded for by the transferred genetic material ,such as antibiotic resistance, after a process called recombination.
