The differences in nucleic acid atomic structure, namely the Hydrogen Bonds - 2 for an AT pair and 3 for a GC pair -, are way too small to be called 'subunits'. Edit Share to:
What is Inderal? Inderal (propranolol) is a beta-blocker. Beta-blockers affect the heart and circulation (blood flow through arteries and veins). Inderal is used to treat tremors, angina (chest pain), hypertension (high blood pressure), heart rhythm disorders, and other heart or circulatory conditions. It is also used to treat or prevent heart attack, and to reduce the severity and frequency of migraine headaches.
Angina (Amlodipine, Felodipine, or Long-Acting Nifedipine) Patients with angina should be treated with a beta-adrenergic blocker. A CCB may be an option when a beta-adrenergic blocker. alone or in combination with a long-acting nitrate is ineffective or contraindicated. Selection of a non DHP CCB (e.g., diltiazem, verapamil) vs. a long-acting DHP in patients not on a beta-adrenergic blocker may depend on patient specific considerations.
