How could lipids lead to a myocardial infarction?
What will be an ideal response?
The fat, arriving via low-density lipoproteins (LDLs), will be deposited on the arterial lining, which stimulates inflammation. The smooth muscle layer of the arteries will enlarge in response to the inflammatory (or defense) cells, and that will result in thickening of the arterial walls. Some defensive cells will take up more lipids, and fatty streaks will form on the arterial wall. These processes produce plaques, which can narrow the passageway within the artery, reducing blood flow. The plaque could rupture, and a blood clot may form. At that point, the artery may be so narrow that the cells it serves will no longer get the oxygen they need and then die. When this happens in the heart, it can cause heart attack.

You are a forensic technician working on a DNA sample obtained from a crime scene. Your job is to compare the unknown DNA sample with known DNA samples collected from five different suspects. Preliminary analysis using only a few DNA markers revealed that the unknown sample could possibly match two of the suspects. After consulting the case file, you find out that these two suspects are brothers (but not twins). You realize that you will have to do a more detailed analysis on the samples so that you can distinguish between the brothers and determine which brothers' DNA matches the unknown sample.Which of the following will help you distinguish between the two final suspects?
A. markers on the Y chromosome B. linkage data C. human genome map D. single nucleotide polymorphisms (SNPs)
