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.
p53 is a key regulator of DNA damage response and can promote DNA repair, apoptosis or cell cycle arrest. It does this by binding to promoters of target genes. It is still not clear what determines when p53 will induce cell cycle arrest versus apoptosis. experimental methods. Apoptotic cells exhibit a particular chemical signature.
