Answer:
A. terminators of replication.
Explanation:

What is myocardial infarction?</h3>
- A myocardial infarction (MI), also referred to as a heart attack, happens when blood flow to the heart's coronary artery is reduced or interrupted, harming the heart muscle.
- The most typical symptom is discomfort or soreness in the chest, which may radiate to the shoulder, arm, back, neck, or jaw. It frequently lasts more than a few minutes and usually happens in the center or left side of the chest.
- Sometimes the discomfort may feel like heartburn. Other signs and symptoms could include fatigue, shortness of breath, nausea, feeling dizzy, and cold sweats.
- Atypical symptoms are present in about 30% of patients. Women more frequently experience arm, neck, or fatigue discomfort instead of chest pain.

The commonly used site to feel a pulse is radial artery on the wrist, the point where radial artery approaches the wrist present at the middle of wrist.
When we placed our fingers in the middle of wrist, we can feel the pulse wave. That is 72 beats per minutes. The radial artery is the site of insertion of the arterial line, for monitoring the blood pressure. It is selected because it is accessible due to the low incidence of the complications such as thrombosis.
The pressure of the blood is always high in the arteries comparative to the veins, usually arteries are present deep in the body, the radial artery in only artery that approaches the skin. Hence, it is used to monitoring the pulses.
