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.
How are lipids formed? A: Lipids are organic compounds that can include substances, such as fats, waxes, phospholipids and steroids. Depending on the type of lipid formed, it can consist of different combinations of molecules including fatty acids, glycerol and phosphate group. Triglycerides, which are a type of fat, are made up of three fatty acids and one glycerol molecule, while phospholipids consist of two fatty acids, one glycerol molecule and a phosphate group.
