Question

Split genes, overlapping genes,house keeping genes in transcription

Answer 1

Answer: In some cases, different exons of a gene code for different active regions of the protein molecule, e.g., in the case of antibodies. Thus, it has been suggested that introns are relics of evolutionary processes that brought together different ancestral genes to form new larger genes.

Answer 2

The coding regions containing actual information of the genes (exons) of most eukaryotic genes are interrupted by few to several noncoding sequences called introns (from intervening sequences) which are spliced out after transcription Such genes are called split genes since their coding sequences are split into several.
