AQA AS biology ticklist 3.4.2 DNA and protein synthesis DNA and protein synthesis Pages The concept of the genome as the complete set of genes in a cell and of the proteome as the full range of proteins that a cell is able to produce. 208 The structure of molecules of messenger RNA (mRNA) and of transfer RNA (tRNA). 209 Transcription as the production of mRNA from DNA. The role of RNA polymerase in joining mRNA nucleotides. 211-212 In prokaryotes, transcription results directly in the production of mRNA from DNA. 212 In eukaryotes, transcription results in the production of pre-mRNA; this is then spliced to form mRNA. 212 Translation as the production of polypeptides from the sequence of codons carried by mRNA. The roles of ribosomes, tRNA and ATP. 213-214 I should be able to relate the base sequence of nucleic acids to the amino acid sequence of polypeptides, when provided with suitable data about the genetic code 215 (Students will not be required to recall in written papers specific codons and the amino acids for which they code.) I should be able to interpret data from experimental work investigating the role of nucleic acids. Page 1 of 1 216
