The basic unit into which the DNA is packed in organisms is the chromosome. These are composed of DNA containing the genetic material and histone proteins which help package them. The DNA having an overall negative charge bonds with the positively charged histone proteins making a complex called chromatin.y admin. DNA vs Chromosome. Nucleic acid constitutes the genetic material of all living organisms. These are polymers made up of sub-units called nucleotides. Nucleotide has three components, a five-carbon sugar, a nitrogen base and phosphoric acid.
The term lipid commonly refers to fats, which are known chemically as triglycerides. Triglycerides are organic molecules that contain three different types of elements: carbon, hydrogen, and oxygen. But technically, lipids are a class of molecules that includes triglycerides, phospholipids, steroids, and waxes. So if you wanted to know what elements are found in lipids as a class, you'd have to allow for phosphorus as well, since phospholipids contain phosphorus in addition to carbon, hydrogen, and oxygen.
Together with carbohydrates and proteins, lipids are the main constituents of plant and animal cells. Cholesterol and triglycerides are lipids. Lipids are easily stored in the body. They serve as a source of fuel and are an important constituent of the structure of cells.Lipids include fatty acids, neutral fats, waxes and steroids (like cortisone).ogether with carbohydrates and proteins, lipids are the main constituents of plant and animal cells.
