<span>Blockage of the Cerebral Artery can reduce blood supply to the brain, causing a stroke (Ishcemic Stroke)
Blood is carried to the brain by two pair of arteries, i) The Internal Carotid arteries, ii) The Vertebral arteries.
Stroke is a neurovascular condition affecting blood vessels in the brain. There are two types of Stroke i) Ischemic Stroke ii) Hemorrhagic Stroke.
In Ischemic stroke occlusion of a cerebral artery causes the damage to brain tissue dependent on blood supply from the affected vessel</span>

Answer:
The bonds that are formed between nitrogenous bases are Hydrogen Bond.
Explanation:
When a hydrogen atom interract with an electronegative atom such oxygen,fluorine hydrogen bond forms,
A single hydrogen bond is weak noncovalent bond but collectively they exerts very strong interraction.
Hydrogen bonding occurs between complementary base pair .For exam An adenine base forms 2 hydrogen bonds with thymine base whereas guanine forms 3 hydrogen bonds with cytosine base.
The hydrogen bonding between complementary is very much important to stabilize the structure of DNA .
