CpG islands [edit]. How methylation of CpG sites followed by spontaneous deamination leads to a lack of CpG sites in methylated DNA. As a result residual CpG islands are created in areas where methylation is rare, and CpG sites stick (or where C to T mutation is highly detrimental). CpG islands (or CG islands) are regions with a high frequency of CpG sites, though objective definitions for CpG islands are limited.
First, you need to become an EMT, which is typically a six month course. EMT certification requires that you be at least 18 years of age, in reasonably good physical shape, and have a high school diploma or GED. Once you become an EMT, paramedic training is typically another 18 months to two years, and 2 and 4 year college degree programs are becoming increasingly common.
So if you have that mindset that you really want to help people and you can over look the bad things, get on the fire department, become a firefighter. And once you become a firefighter, they'll offer you a chance to become a paramedic. If you take that advantage and become a paramedic, it's a very interesting job.
