When epigenetics meets alternative splicing: the roles of DNA
... “DNA methylation can participate in chromatin remodeling and is also found in its highest abundance at exon boundaries.” Thus, even in exons that have the same GC content as their flanking introns, the CpG dinucleotide is more common in exons than introns. This elevated CpG abundance causes, in turn ...

Point mutation
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
