Dig out a ditch where your French drain will go. A standard French drain ditch is about 1.5 feet deep and 10-12 inches wide, varying based on the size of the pipe chosen (usually 4-6 inches) and the desired depth. Line the ditch on all sides with landscape fabric to prevent soil erosion.
1 A gene is a small section of DNA that contains the instructions for a specific molecule, usually a protein. 2  The purpose of genes is to store information. 3  Each gene contains the information required to build specific proteins needed in an organism.enes are small sections of DNA within the genome that code for proteins. They contain the instructions for our individual characteristics â like eye and hair colour.
The Genetic Code in DNA. The instructions for the construction of proteins is written in DNA using the genetic code. More specifically, the sequence of bases bonded to the sugar phosphate backbone of the double helix contains information in the form of three-base codons that specify the sequence of amino acids to be used in the construction of proteins.
