Genetics

At www.sciencenews.org/view/generic/id/65063/title/Central_dogma_of_genetics_maybe_not_so_central/ ... It seems the RNA molecules aren't always faithful reproductions of the genetic instructions contained within DNA, a new study has shown. This contradicts a major tenet of genetics - a central dogma that is that DNA letters encode information and RNA is produced in DNA's likeness. The RNA then serves as a template to build proteins. However, this study suggests otherwise - RA does not replicate DNA exactly.
