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.
Our bodies are made up of millions of cells (100,000,000,000,000), each with their own complete set of instructions for making us, like a recipe book for the body. This set of instructions is known as our genome and is made up of DNA. Each cell in the body, for example, a skin cell or a liver cell, contains this same set of instructions: The instructions in our genome are made up of DNA. Within DNA is a unique chemical code that guides our growth, development and health. This code is determined by the order of the four nucleotide bases that make up DNA, adenine, cytosine, guanine and thymine, A, C, G and T for short. DNA has a twisted structure in the shape of a double helix. Single strands of DNA are coiled up into structures called chromosomes. Your chromosomes are located in the nucleus within each cell.
