Error Correction: There is an error in this post "DNA is read from the 5' end to the 3' end in groups of three bases." Should read "DNA is read from the 3' end to the 5' end in groups of three bases called codons..."

DNA is replicated in the 5' to 3' direction not read in that direction. One is in terms of the strand being read the other is in terms of the new strand being created.
