Answer:
It allows the single gene to code for multiple proteins.
Step-by-step explanation:
The primary transcript formed by transcription in the nucleus of eukaryotes under post-transcriptional modifications. One such modification is the removal of introns and joining of exons together. The mature mRNA after these modifications enter the cytoplasm to serve as a template for protein synthesis.
Alternative splicing is the differential splicing process that produces mRNA with different combinations of exon from a single primary transcript. These mRNA molecules with different combinations of exons code for different proteins. Therefore, alternative splicing allows the formation of cell specific or developmental stage specific variants of proteins from a single gene in a eukaryotic cell.
