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 instructions that are used to build and maintain an organism are arranged in an orderly manner in strands of DNA. Within the nucleus are threads of chromatin composed of DNA and associated proteins ([link]). Along the chromatin threads, the DNA is wrapped around a set of histone proteins.
