[Diapositiva 1] UNIT 2. THE FOUNDATIONS OF GENETIC INHERITANCE [Diapositiva 2] [Diapositiva 3] 1. NUCLEIC ACIDS • Definition : Macromolecules formed by the union of simpler molecules or monomer called nucleotides , that contain genetic information and control the protein synthesis. • Types of nucleic acids: [Diapositiva 4] 1. NUCLEIC ACIDS Structure of nucleotides: Pentose: - A sugar with 5 carbon atoms. - Types: Ribose (ribonucleotides) o deoxyribose (deoxyribonucleotides). Nitrogenous base: - Types: Derived from purine (A y G) or pyrimidine (C, T y U). H 3 PO 4 group. [Diapositiva 5] 1. NUCLEIC ACIDS ACTIVITY 1 [Diapositiva 6] 1. NUCLEIC ACIDS Function of nucleotides: Forming nucleic acids . Other important functions for living things. Function of nucleic acids: Regulating cell activity (protein synthesis process). Transferring genetic information. [Diapositiva 7] 1. NUCLEIC ACIDS Formation of nucleic acids: DNA and RNA. Phosphodiester bond : covalent bond between a phosphate group of one nucleotide and the pentose of another , forming chains or strands of: – H3PO4 – pentose – H3PO4 – pentose – H3PO4 [Diapositiva 8] 1.
