Scientists have found that memories may be passed down through generations in our DNA. New research from Emory University School of Medicine, in Atlanta, has shown that it is possible for some information to be inherited biologically through chemical changes that occur in DNA.
Concept 25 Some viruses store genetic information in RNA. DNA was believed to be the sole medium for genetic information storage. Furthermore, Watson and Crick's central dogma assumed that information flowed one-way from DNA to RNA to protein.So it came as a surprise when in 1971, it was discovered that some viruses shift their genetic information from RNA to DNA.oncept 25 Some viruses store genetic information in RNA.
