Watson and Crick DNA Model DNA stands for Deoxyribonucleic acid which is a molecule that contains the instructions an organism needs to develop, live and reproduce. It is a type of nucleic acid and is one of the four major types of macromolecules that are known to be essential for all forms of life. DNA Model The three-dimensional structure of DNA, …
Nucleic Acids- Nucleosides and Nucleotides Nucleotide is any member of the class of organic compounds in which the molecular structure comprises a nitrogen-containing unit (base) linked to a sugar and a phosphate group. They are monomeric units of nucleic acids and also serve as sources of chemical energy (ATP, GTP), participate in cellular signalling (cAMP, cGMP) and function as important cofactors of enzymatic reactions …
