Question: In eukaryotic cells, the initial RNA transcript, known as pre - mRNA, contains both coding sequences ( exons ) and noncoding sequences ( introns )

In eukaryotic cells, the initial RNA transcript, known as pre

-

mRNA, contains both coding sequences

(

exons

)

and noncoding sequences

(

introns

) .

Before the mRNA can be translated into a protein, these noncoding sequences must be removed to produce a mature mRNA molecule. Considering the various steps involved in RNA processing, which specific process is responsible for excising the introns from pre

-

mRNA to ensure the correct assembly of the coding sequence?

Group of answer choices

DNA replication

RNA splicing
