The spliced product of heterogenous nuclear rna will be made and exported out of this cellular structure(s).

the so called Alternative splicing, or differential splicing, is a regulated process during gene expression that results in a single gene coding for multiple and many proteins. In this process, minimal parts of a gene may be included within or excluded from the final, processed RNA (mRNA) which is the messenger that produced that gene. In this way, the proteins that are translated from  spliced mRNAs will contain differences in their amino acid sequence and also, in their biological functions. Furthermore, this process called alternative splicing allows the human genome to direct the synthesis of many more proteins as well.
