Why can alternative splicing of messenger RNAs (mRNAs) be advantageous for eukaryotic organisms? A-allows exons from two different genes to be spliced into a new mRNAB-increases the variety of proteins that can be producedC-decreases the average gene length in eukaryotesD-allows for smaller genomes than prokaryotesE-removes exons instead of introns from newly transcribed mRNA

The correct answer is A allow exons from two different genes to be spliced into a new mRNA B increases the variety of proteins that can be produced.

Explanation:

Alternative splicing is one of the most important RNA splicing process that occurs in eukaryotic cells.

Alternative splicing of an mRNA allow the later to encode multiple proteins thus increasing the diversity of that encoded protein.

During alternative splicing a specific coding segment or exon can be either included or excluded from the mRNA that is already being processed.

Alternative splicing is under tight regulation of trans acting element thaose interact with the cis acting sites of the mRNA transcript.
