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.
Safety. Because EMS Safety is an adult-education based course, the minimum recommended age for certification is 13 years old. However, if a student can understand the information and pass the written and skills testing, then he or she should be issued a certification card regardless of his or her age.
