<span>Organisms all possess DNA as their genetic material. What differentiates them (and their DNA) is the sequence of base-pairs within the DNA. The base-pairs are actually specific sequences of nucleotides (i.e. adenine , thymine, guanine and cytosine, labelled A, T, G, and C respectively) which encode genes. In other words, the DNA in each organism is made of these bases, but their sequences differ from organism to organism.</span>
How does a new hypothesis replace an older explanation of something in the natural world? To understand this let us look at one of the classical example of geocentric theory and heliocentric theory. The geocentric theory states the Earth is at the centre of the solar system and the Sun, Moon, and all the other planets revolve around it. This ancient theory failed to explain the phenomenon like the phases of Moon, solar eclipse and lunar eclipse. The modern heliocentric theory which states that the Sun is at the centre of solar system, and all the planets including the Earth revolve around it. This theory was able to explain all the phenomenons unlike the geocentric theory. Hence the heliocentric theory replaced the geocentric theory.
A "beta-blocker" or clotbuster are the types of medication used to dissolve clots involved in MIs and CVAs. Remember though to be aware that two other medications that are used to prevent further clot build up are not clot busters but instead vasodilators (Nitroglycerin) or clotting antagonist (Aspirin).
