What happens during splicing?
In hnRNA transcript, intron regions are removed and exon regions are joined together.
Exons are removed and introns are joined together during the processing of hnRNA.
Some exons of hnRNA are removed and all introns and remaining exons are joined together
Exons and introns are arranged alternately.
Splicing is a process where the introns are removed and exons are joined in a defined order.
