It is estimated that 99 percent of all production problems in crawfish ponds are related to poor water quality. Dissolved oxygen (D.O.) is the most serious problem, but pH, total hardness, total alkalinity, ammonia, nitrite, hydrogen sulfide, and iron can also affect crawfish production.
DNA Land is a place where you can learn more about your genome while enabling scientists to make new genetic discoveries for the benefit of humanity. Our goal is to help members to interpret their data and to enable their contribution to research.
DNA can be found inside the nucleus of every cell, apart from red blood cells. It's tightly wound and spread throughout the 46 chromosomes. One set of 23 chromosomes is inherited from each parent.Inside the chromosomes the DNA exists as genes.lants and Animals. In plants and animals DNA is also found in the cell nucleus. The DNA of all animals is very similar. The major differences are in the number of chromosomes and genes, and the arrangement of base pairs within these genes.
