Vedclass · Answer

(B) Assertion $A$ is true because bacteria exhibit diverse phenotypic traits,such as antibiotic resistance or metabolic capabilities,often determined by extra-chromosomal genetic elements.Reason $R$ is true because many bacteria contain small,circular,extra-chromosomal $DNA$ molecules known as plasmids,which are distinct from the genomic $DNA$.However,while plasmids provide unique phenotypic characters (like antibiotic resistance),the presence of plasmid $DNA$ is not the sole reason for all unique phenotypic characters in bacteria. Therefore,$R$ is a true statement but does not provide the complete or direct explanation for the general phenotypic diversity mentioned in $A$.

Column-$I$	Column-$II$
$(A)$ Halophiles	$(I)$ Gram-negative bacteria
$(B)$ Thermoacidophiles	$(II)$ Inhabit extremely salty areas
$(C)$ Spirochaetes	$(III)$ Responsible for methane production
$(D)$ Firmicutes	$(IV)$ Survive in acidic and high-temperature conditions
	$(V)$ Gram-positive bacteria

Assertion $A$: Some bacteria possess unique phenotypic characters.
Reason $R$: Many bacterial cells contain plasmid $DNA$ in addition to genomic $DNA$.
