Question

Which of the following does not occur during protein synthesis in eukaryotes?

• A. Formation of hnRNA
• B. Splicing
• C. Transport of $m$ RNA from cytoplasm to nucleus
• D. Capping

Answer 1

The correct option is C Transport of $m$ RNA from cytoplasm to nucleus

During protein synthesis, mRNA is synthesised from DNA. The initially formed mRNA is called primary transcript (hnRNA).
It undergoes modifications such as splicing, capping and tailing to form the functional mRNA. This newly synthesised mRNA moves from nucleus to cytoplasm.
