Scientists analyze chromosomes 2 and 4

... the researchers identified a messenger RNA (mRNA) transcript from a gene on chromosome 2 that possibly may produce a protein unique to humans and chimps. Scientists have tentative evidence that the gene may be used to make a protein in the brain and the testes. The team also identified "hypervariable" regions ...

Splicing (genetics)

...ntrons, eukaryotes initially create a primary mRNA transcript called pre-mRNA that is composed of both introns and exons (see transcription ).
