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.
Lipids constitute a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, and others. The main biological functions of lipids include energy storage, signaling, and acting as structural components of cell membranes.ipid. Any of a group of naturally occurring molecules. Lipids include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, phospholipids, and others.
