Ribonucleic acid is important in all living cells, as it transfers genetic information from DNA to ribosomes. RNA is a polymer of nucleotides formed by condensation, with phosphodiester between nucleotides. Each nucleotide is formed from a ribose, a nitrogen-containing organic base and a phosphate group. An RNA molecule is a relatively short polynucleotide chain. Ribosomes are made of RNA and proteins. 0.2 weeks Explain the role of RNA in transferring genetic information and as a component of ribosome Describe the structure of RNA and identify structural components of an RNA nucleotide from diagrams. Compare and contrast the similarities and differences between DNA and RNA. Learning activities: teacher explanation of types of RNA and their roles, with focus on ribosomal and messenger RNA comprehension on RNA structure. Students highlight differences to DNA teacher explanation of RNA structure related to function provide DNA sequence and ask students to produce the complementary mRNA sequence exam questions. Skills developed by learning activities: AO1 – development of knowledge and understanding AO2/AO3 – interpreting DNA sequence and applying knowledge to work out complementary mRNA code. Exampro: BYA3 – Jan 2003 Q1a BYB2 – June 2009 Q3a–3c Rich questions: why can we not work out the frequency of bases in RNA when provided with data about the frequency of some of the other bases? how does the single-stranded structure of RNA suit its role in transferring genetic information to the ribosomes? 3.1.5.2 DNA replication Prior knowledge:
