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.
The nucleus is the control center of a cell. The nucleus controls the cell's growth and reproduction and contains the cell's DNA. The nucleus of a cell contains most of that cell's genetic material. Its job is to maintain the integrity of the cell while controlling its activities. The nucleus is separated from the cytoplasm by a membrane called a nuclear envelope.This helps to protect the cell's chromosomes which is where the DNA is located. The nucleus was first discovered by microscopist Antonie van Leeuwenhoek in the mid-1600s while he was examining the red blood cells of salmon.
