Capsid is the component of a virus that is lacking in its cell
A capsid is the protein shell that surrounds a virus. Capsids functions by protecting the nucleic acids of a virus while interacting with the host environment. Capsids are made up of many oligomeric structural subunits that contains the protein; protomers. Capsids are generally grouped based on their structure. The common ones are helical and icosahedral.
Answer:
The correct answer will be option A.
Explanation:
The electrical impulses are generated in the sino-atrial node or SA node, a mass of cells which generates impulse in the upper atrium.
This electrical impulse transmits from the sino-atrial node to the atrio-ventricular node in the lower portion of the upper atrium through the internodal pathway- the pathway composed of atrial cells.
Once the impulse reaches the AV node, it is transferred to the ventricular portion of the heart through Bundle of His presence in the ventricular septum. This bundle of his divides into left and right ventricles through bundle branches and stimulates both the ventricles.
Thus, option-A is the correct answer.
