Question
Chapter 25, Problem 9PP
Interpretation Introduction
Interpretation:
The structural formula showing pairing between the uracil’s keto form and adenine is to be written.
Concept Introduction:
During transcription, the adenine present on the template strand of the DNA (deoxyribonucleic acid) pairs with the uracil on the synthesized mRNA (messenger ribonucleic acid). mRNA is distinguished from DNA in the manner such that it consists of uracil
