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.
DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a polynucleotide.. Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.he deoxyribose sugar of the DNA backbone has 5 carbons and 3 oxygens. The carbon atoms are numbered 1', 2', 3', 4', and 5' to distinguish from the numbering of the atoms of the purine and pyrmidine rings. The hydroxyl groups on the 5'- and 3'- carbons link to the phosphate groups to form the DNA backbone.
