Document Summary
Define the relationship between genes and polypeptides. Describe the flow of information through cells. Summarize the steps in all stages of transcription: pre-initiation complex, initiation, elongation and termination. Summarize the processing of hnrna to mature mrna, emphasizing the importance of the 5" cap, the poly(a) tail and splicing together of exons. Define the different types of rna, contrasting the roles of mrna, rrna and trna. Describe the properties of the genetic code and the codon assignments. Define the role of trnas in decoding the genetic code. Summarize the steps in all stages of translation: trna charging, initiation, elongation and termination. Transcription = synthesis of complementary rna from a dna template in the nucleus. Transcription happens in the nucleus and translation happens in the cytosol end up with premrna after transcritption which goes through post-transcriptional modifications so that it can leave the nucleus through specialized proteins transporters.
