STRUCTURE DNA & RNA PREPARED BY: MARY CLAIRE A. FLORES STUDENT TEACHER Learning Competency: Describe the structure of DNA & RNA molecule learning objectives At the end of the 60- minute lesson, the students are expected to achieve the following objectives with at least 85 % of level profiency; 11. Define DNA and RNA; 2. Describe the structure of DNA and RNA molecule 3. Differentiate DNA from RNA in terms of their structure, components, functions and locations DNA RNA STRUCTURE Double-stranded Helix Single Stranded COMPONENTS Sugar Deoxyribose, phosphate and nucleotides basis ; A, T, C, G Sugar Deoxyribose, phosphate and nucleotides basis: A, U,C, G FUNCTIONS Stores genetic materials Function in protein synthesis transcribing and translating the genetic code LOCATION Nucleus Cytoplasm DEOXYRIBONUCLEIC ACID DNA is a molecule that contains the instructions an organism needs to develop, live, and reproduce. DNA is found mainly in the nucleus of the cell. DEOXYRIBONUCLEIC ACID DNA is a long-thin molecule made up of nucleotides. Each nucleotides contains; ·Phosphate Groups ·The sugar DEOXYRIBOSE and Nitrogenous bases: Adenine (A), Thymine (T) Cytosine (C), Guanine (G) RIBONUCLEIC ACID RNA, just like DNA, is made of nucleotides. Each nucleotide is composed of ·Phosphate group ·The sugar ribose and Nitrogenous bases Adenine (A), Uracil (U) Guanine (G), Cytosine (C) DEOXYRIBONUCLEIC ACID RNA is used to translate instructions from DNA to make proteins. RNA in turn then contains the codes for the primary sequence of amino acids to make proteins. 1. Messenger RNA (mRNA) transcribes the DNA nucleotide bases to RNA nucleotide bases 3 types of rna 2. Ribosomal RNA (rRNA) binds the mRNA and tRNA to ensure that codons are translated correctly 3. Transfer RNA (tRNA) translates the mRNA codons into the correct amino acids. Any questions? THANK YOU
