You are studying a large eukaryotic gene that is 439,515 base pairs long. You find the polypeptide that this gene produces in liver cells is 46,771 amino acids long. Your colleague studies the function of this gene in brain cells, and finds the polypeptide produced in the brain is much larger – 61,438 amino acids long. How do you explain this difference? Possible Answers: A. The cell cycle of liver cells is much longer than that of brain cells. B. This is due to alternative splicing. in the brain C. There was a different complement of sequence-specific transcription factor binding sites in the CRM of the brain cells. D. There is no 5' cap added to the gene product from the liver cells.

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.
