High cholesterol<span> can lead to the buildup of plaque in </span>artery<span> walls. This buildup is called atherosclerosis. It can lead to coronary </span>artery<span> disease (CAD), heart attack, stroke or transient ischemic attack (TIA), and peripheral </span>arterial<span>disease</span>
Answer: Option B) phosphate; hydroxyl; 3'
We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'
carbon atom
Explanation:
For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).
While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.
Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group
