Final answer:
The molecule with genetic information is DNA. It lacks a simple molecular formula due to its complexity and consists of covalent bonds in its structure.
Step-by-step explanation:
The molecule being referred to appears to be Deoxyribonucleic Acid (DNA). This organic molecule contains genetic information crucial for the development and functioning of all living organisms. DNA is responsible for determining one's physical characteristics, such as eye color and facial features. It encapsulates the instructions for building proteins that carry out a plethora of functions within the body.
Molecular formula: Since DNA is a complex macromolecule made up of repeating units called nucleotides, each consisting of a sugar (deoxyribose), a phosphate group, and a nitrogenous base, it does not have a simple molecular formula like smaller compounds do.
Type of substance: DNA molecules are held together by covalent bonds, where atoms share electrons. Specifically, the backbone of the DNA molecule is made up of sugar and phosphate linked by covalent bonds, and the nitrogenous bases pair through hydrogen bonds.
