Nucleoid region. Definition. noun. The area within a prokaryotic cell where the genetic material is to be found. Supplement. Prokaryotes are characterized by their lack of a ââtrueââ nucleus.In stead of a nucleus, they have a nucleoid where their genetic material is localized.

Nucleic acids are the molecules that carry the genetic information that is passed down from parent to child. However, nucleic acids are special since they can also combine with proteins to become the machines -- called ribosomes -- that turn genetic instructions in nucleic acids into other protein machines. Nucleic acids are linked together into a chain. DNA is made of two chains that connect like a rope ladder.
Carbohydrates: Carbohydrates are organic compounds made of  carbon, hydrogen, and oxygen atoms. Carbs are made of  monosacharrides (single sugars) linked together. Thei â¦ r function is  to provide a key source of energy for cells. An example is starch,  made of many linked glucose molecules.   2. Lipids: Lipids are nonpolar molecules that are not soluble in  water. They include fats, phospholipids, steroids, and waxes.  Lipids' functions are to provide energy and serve an important part  in the structure and functioning of cell membranes.  4. Nucleic acids: Nucleic acids are long chains of smaller  molecules called nucleotides. Nucleic acids mainly serve the  purpose of providing the organism with its genetic blueprint and  coding. They basically tell you who you are.DNA and RNA are two  types of nucleic acids.
