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.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.eoxyribonucleic acid or DNA is a molecule that contains the instructions an organism needs to develop, live and reproduce. These instructions are found inside every cell, and are passed down from parents to their children.
