Concept explainers

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.

Expert Solution

Step 1

The specialized pacemaker cells in the heart are responsible for the current generation. A specialized conducting tissue allows the unidirectional flow of electrical impulses from these pacemaker cells. These impulses stimulate the contraction of cardiac muscles via intracellular events that involve calcium.
