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.
Making the world better, one answer at a time. The nucleoid is a region of cytoplasm where the chromosomal DNA is located. It is not a membrane bound nucleus, but simply an area of the cytoplasm where the strands of DNA are found.Most bacteria have a single, circular chromosome that is responsible for replication, although a few species do have two or more.aking the world better, one answer at a time.
