The biggest difference between elements and molecules is that elements only have one TYPE of atom, while molecules have MULTIPLE types of atoms. True False
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
- Atoms and molecules are important in biology because they are the basic building blocks of all living organisms.
- In biology, atoms are used to create the molecules, such as proteins, carbohydrates, lipids, and nucleic acids, that make up the various structures and capabilities of living things.
- Understanding the basic biology of living things requires knowledge of the structure and function of atoms and molecules.
