Question

Which among the following is a characteristic of a monocistronic mRNA

• A. Has codons capable of synthesizing only a single protein
• B. Combines with only a single tRNA
• C. Has codons capable of synthesizing multiple protein.
• D. Has multiple codons

Answer 1

Answer: (A), (B)

The correct options are
A Has codons capable of synthesizing only a single protein
B Combines with only a single tRNA

A monocistronic mRNA carries the genetic code to translate only a single protein and is translated by a single tRNA while a polycistronic RNA is translated by several tRNAs into more than one protein.
