Cell reproduction begins with DNA replication
• See Ch 14 for details
• Know: basic structure of DNA: double stranded, antiparallel starnds, pyrimidine
and purine bases and their pairing rules;
• Know: RNA structure: single stranded, pyrimidine and purine bases, given a
stretch of DNA code you should be able to give the corresponding mRNA that
HOW DO CHROMOSOMES MOVE?
• See expmt. in Fig 11.11. Do you understand why we think that the spindle fibres
shorten by removal of tubulin units from the kinetochore end?
• Also note the model structure in Fig. 11.12. What data supports this structure?
Based in the model do you expect chromosomes movement to use up ATP?
• Mechanism of reproduction (asexual) for eukaryotic cells. Binary fission its
equivalent in prokaryotes.
• Crucial mechanism in growth and repair of multicellular organisms
Proteins: - enzymes
- structural (hair, bone)
- defence (antibody system)
