Vedclass · Answer

(A) The distance between two consecutive base pairs in $DNA$ is $0.34 	ext{ nm}$ or $0.34 	imes 10^{-9} 	ext{ m}$.Given,the number of base pairs = $10,000$ or $10^4$.The total length of $DNA$ = (Number of base pairs) $	imes$ (Distance between two consecutive base pairs).Length = $10^4 	imes 0.34 	imes 10^{-9} 	ext{ m}$.Length = $0.34 	imes 10^{-5} 	ext{ m}$ or $3.4 	imes 10^{-6} 	ext{ m}$.Since $3.4 	imes 10^{-6} 	ext{ m}$ is the calculated value,and option $A$ is $3.4 	imes 10^{-6} 	ext{ m}$,the correct answer is $A$.

$A$ $DNA$ molecule contains $10,000$ base pairs. What will be the length of this $DNA$ molecule?
