The Bassoon double reeds are broader and shorter than the oboe double reeds, so they do not need a tight embouchure to produce sound. Almost all the double reed embouchures are similar and the musicians need to pull their lips over their teeth to protect the reed from their teeth. Â© 2015 Music & Arts. All rights reserved.

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 31 Some DNA does not encode protein. In most cases when DNA is extracted from living cells, the proteins (including histones) are dissolved away. This results in long strands of naked DNA, which retain their genetic information. So it is useful to visualize a chromosome as a continuous strand of DNA. Arrayed along the DNA strand are the genes, specific regions whose sequences carry the genetic code for making specific proteins.
