Question

A DNA strand is directly involved in the synthesis of all of the following except:

• A. Proteins
• B. DNA
• C. mRNA
• D. tRNA

Answer 1

The correct option is A

Proteins

One strand of DNA serves as a template for the synthesis of new DNA during replication. It is also involved in the syntheis of different types of RNA, such as mRNA and tRNA. The process during which mRNA is synthesised from DNA is known as transcription. This mRNA acts as template for the synthesis of proteins. Hence, the correct answer is proteins, as DNA is not involved directly.
