"The Double Helix"

Download file to see previous pages As a result, a replication of the original DNA is achieved with the parent and daughter molecules having exactly the same properties. The double helix in the complementary based pairing therefore ensures that daughter molecules derive exactly the same characteristics as the parent molecules (Teerikorpi, Valtonen, Lehto, Byrd and Chernin, 2008).
The phrase, ‘two strands of DNA in the double helix are antiparallel,’ means that the strands run in opposite directions. This is because of properties of the different structures of the strands that ensure the opposite directions for bonding in the double helix strands (Strachan, 2003). If the strands were parallel, the ends of the double helix strands would have similar properties. This would result from the strands pairing with both strands aligned in the same direction as opposed to the opposite directional stranding of the ‘antiparallel’ double helix strands (Behr, ...Download file to see next pagesRead More

The importance of Hydrogen Bonding in Biology
This bond forms when a hydrogen atom binds to a strong electronegative atom of one molecule at the same time it covalently attaches to another electronegative atom in a different molecule (Chang, 2008). The electronegative atoms that form this kind of bond with hydrogen include oxygen, fluorine and nitrogen.
