Adenine on One Strand of D NA Forms

Question

Adenine on one strand of D NA forms
A) Three hydrogen bonds with guanosine on tRNA
B) Covalent bonds with rRNA
C) Two hydrogen bonds with thymine on tRNA
D) Two hydrogen bonds with cytosine on tRNA
E) Two hydrogen bonds with uracil on tRNA

Accepted Answer

Adenine forms two hydrogen bonds with uracil on RNA, including tRNA. In DNA, adenine pairs with thymine through two hydrogen bonds, but in RNA, thymine is replaced by uracil.
