Vedclass · Answer

(B) In a $DNA$ double helix,adenine $(A)$ pairs with thymine $(T)$ via $2$ hydrogen bonds $(A=T)$.Given that the $DNA$ fragment contains $10$ thymine $(T)$ bases,and assuming it is a double-stranded $DNA$ molecule where each $T$ is paired with an $A$,there will be $10$ adenine bases as well.Since each $A-T$ base pair consists of $2$ hydrogen bonds,the total number of hydrogen bonds for $10$ $A-T$ pairs is $10 	imes 2 = 20$.Therefore,the correct answer is $20$.

What is the number of $H$-bonds in a $DNA$ fragment containing only $10$ thymine bases?
