The sudden blood clot that forms over the rupture then causes a heart attack or stroke. Blocked arteries caused by plaque buildup and blood clots are the leading cause of death in the U.S. Reducing cholesterol and other risk factors can help prevent cholesterol plaques from forming.Occasionally, it can even reverse some plaque buildup.he sudden blood clot that forms over the rupture then causes a heart attack or stroke.

Nucleotides. A single nucleotide contains a phosphate group, deoxyribose or ribose (depending on the nucleic acid) and a nitrogen base, which can be adenine, guanine, cytosine â¦ , thymine, and uracil. These monomers combine to form polymers known as DNA or RNA.
Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants, in the chloroplast.In humans, the 16,600 base pairs of mitochondrial DNA encode for only 37 genes.Human mitochondrial DNA was the first significant part of the human genome to be sequenced. In most species, including humans, mtDNA is inherited solely from the mother.n humans, the 16,600 base pairs of mitochondrial DNA encode for only 37 genes.
