RNA STRUCTURE AND FUNCTION Dr. Preetha J Shetty September 18, 2024 www.gmu.ac.ae COLLEGE OF Learning Objectives Describe the biochemical structure of ribonucleotides Describe the similarities and differences between RNA and DNA Describe the functions of the three main types of RNA used in protein synthesis Explain how RNA can serve as hereditary information RNA Structure RNA is typically single stranded and is made of ribonucleotides that are linked by phosphodiester bonds. A ribonucleotide in the RNA chain contains ribose (the pentose sugar), one of the four nitrogenous bases (A, U, G, and C), and a phosphate group.  DNA Vs RNA (a) DNA is typically double stranded, whereas RNA is typically single stranded. (b) (b) Although it is single stranded, RNA can fold upon itself, with the folds stabilized by short areas of complementary base pairing within the molecule, forming a three-dimensional structure.  DISCLAMER The contents of this presentation, can be used only for the purpose of a Lecture, Scientific meeting or Research presentation at Gulf Medical University, Ajman. www.gmu.ac.ae
