During transcription, Adenosine forms a base pair with Uracil instead of Thymine.(a) True(b) FalseI had been asked this question in an interview for internship.I need to ask this question from Transcription Basics topic in section Molecular Basis of Inheritance of Biology – Class 12

Answer»

Correct choice is (a) True

To elaborate: In DNA, the double hydrogen base pairing is seen between Adenine and THYMINE. Likewise, the TRIPLE hydrogen base pairing is seen between Guanine and Cytosine. But Uracil is present in the PLACE of Thymine in the single stranded structure of RNA. So, Adenosine forms a base pair with Uracil INSTEAD of Thymine.
