WebThe Use of Water in Living Organisms Water is a molecule made up of one oxygen and two hydrogen molecules covalently bonded together. The oxygen is partially negative and the hydrogen is partially positive, making up the main feature of water- its ability to form hydrogen bonds. Hydrogen bonding is formed from the dipole-dipole attraction between a … WebOct 7, 2024 · DNA or deoxyribonucleic acid is a type of molecule known as a nucleic acid.

WebAccording to Chargaff's rule, the amount of adenine (A) in a DNA molecule is equal to the amount of thymine (T), and the amount of guanine (G) is equal to the amount of cytosine (C). Therefore, if a DNA molecule is 20% Guanine (G), then: Adenine (A) also represents 20% of the DNA molecule, since A=T. WebDNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, protists, archaea and bacteria. It is made up of two polynucleotide chains in a double helix. [1] DNA is in each cell in the organism and tells cells what proteins to make. Mostly, these proteins are enzymes. shirt you can tan through
