DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). <span>DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.</span>
Answer:
Red blood cells and blood plasma do not contain DNA. Red blood cells don't have the DNA containing nucleus and mitochondria. Only white blood cells in blood contain DNA. With blood donation, usually most of the white blood cells are filtered out.
Explanation:
because red blood cells don't have the DNA containing nucleus and mitochondria

- Heating the water if run by steam by pumping the waste into rivers
- The clean water act focuses on navigation and water as in fishing, and swimming water while the safe drinking water act dictates how water comes to our cups from their original sources.
- You can get information by any sites locally about disposing chemical waste or any government website ending in .gov
- Home waters including sewage have to be filtered through heavy chemical processes using extra waters and factories. our clean water volume is plummeting.
Answer:
Four satellites are needed to find your location. GPS's get the signal from satellites and that can calculate the distance you are from those satellites and location. the satellites emit high frequency low power signals that your GPS can pick up.
