First and most obvious one was is constant use of tobacco. Smoking can damage blood vessels and that can lead to blockages within the vessels. The single most important risk factorthough is his high blood pressure. The fact that he was skipping his meds was also not helpinghis chances. He also presented with high cholesterol which greatly increases the chances of blockages within the vessels.44.
B.Incorrect. When transcription is transcribed from the gene for transcription, only a string of DNA is used as a template by the RNA polymerase.
Answer:
Microarray technology is a very useful technology that allows to study the measure the expression levels of large numbers of genes simultaneously. It consists of a solid support (that can be glass, silice, or nylon), and to it are attached a lot of single stranded DNA fragments that acts like probes. By complementarity, the genes corresponding to this probes that are being expressed at some time will attach to it. Probe-target hybridization is usually detected and quantified by detection of a fluorophore compund, a silver stained, or chemiluminescence-labeled targets.
