It is easier to dig and grade a wide French drain, especially when deep, because you can get your digging tools, hands, and even feet into a deep 12 inch trench - but not a 6 inch one. Grading the bottom of trench to obtain the proper slope is also much easier in a wider French drain, especially when digging by hand.
The nucleus of a cell contains chromosomes, which carry genetic information in a long molecule called DNA. Genes are regions of DNA that carry the code to control a particular cell activity or the production of a particular protein. gene is a section of DNA which controls part of a cell's chemistry-particularly protein production. is a shorter region of DNA that carries the genetic code for a particular characteristic or cell activity. Nucleus, chromosome and gene. DNA molecules contain chemicals called bases.
DNA is the molecule that encodes the genetic instructions enabling a cell to produce the thousands of proteins it typically needs. The linear sequence of the A, T, C, and G bases in what is called coding DNA determines the particular protein that a short segment of DNA, known as a gene, will encode. But in many organisms, there is much more DNA in a cell than is needed to code for all the necessary proteins. This non-coding DNA was often referred to as junk DNA because it seemed unnecessary. But in retrospect, we did not yet understand the function of these seemingly unnecessary DNA sequences. We now know that non-coding DNA can have important functions other than encoding proteins.
