1 JYC: CSM17 BioinformaticsCSM17 Week 5: DNA and Genetics Genetics Cell Structure DNA Transcription (->RNA) Protein Structure

2 JYC: CSM17 Genetics Gregor Mendel (1865) Chromosomes –46 in humans Reproduction –female has XX –male has XY

3 JYC: CSM17 Cell Structure Nucleus & cytoplasm Mitochondria Chloroplasts Endoplasmic reticulum

4 JYC: CSM17 DNA - history Watson & Crick (1953) The double helix (like a twisted ladder)

5 JYC: CSM17 DNA - copying Replication DNA polymerase

6 JYC: CSM17 DNA - structure double helix (spiral) sugar-phosphate backbone nucleotide bases Adenine (A) Guanine (G) Cytosine (C) Thymine (T)

7 JYC: CSM17 Prokaryotes (simple cells) Circular DNA Mitochondria (in animals, plants, fungi) Chloroplasts (in plants) Endosymbiosis... leads to Eukaryotes

8 JYC: CSM17 Transcription - reading the data enzyme - transcriptase gene opens up and... messenger RNA is formed mRNA moves off through nuclear pores......to the ribosomes
