Analyze Genome Maintenance Processes: Describe the molecular mechanisms of DNA replication in prokaryotes and eukaryotes, including key enzymes and fidelity control systems. Explain the Flow of Genetic Information: Illustrate the processes of RNA transcription and maturation (mRNA, tRNA, rRNA) and the general mechanisms of transcriptional regulation in various organisms. Interpret the Genetic Code and Protein Synthesis: Comprehend the genetic code and describe in detail the translation of genetic information into proteins, in both prokaryotes and eukaryotes. Recognize Levels of Gene Expression Regulation: Analyze the post-transcriptional regulatory mechanisms of gene expression, including regulatory RNAs and their roles. Identify Genetic Recombination Mechanisms: Explain the processes of genetic recombination (site-specific and homologous) and transposition, understanding their biological significance. Know the Genetic Specificities of Organelles: Describe the peculiarities of mitochondrial and chloroplast DNA and their evolutionary and applied implications. Skills and Autonomy Correlate Structure and Function: Connect the structure of biological molecules to their roles in the fundamental processes of molecular biology.
