Presentation Transcript

  1. Chapter 9 and some of 8DNA and the Molecular Structure of Chromosomes

  2. The Structures ofDNA and RNA DNA is usually double-stranded, with adenine paired with thymine and guanine paired with cytosine. RNA is usually single-stranded and contains uracil in place of thymine.

  3. nucleotide = sugar + base + phosphate nucleoside = sugar +base When Do we Find RNA Mixed with The DNA?

  4. Ribonucleotide Reductase

  5. Pyrimidines have the longer name and smaller base Purines have the shorter name and bigger base

  6. Structure of aPolynucleotide Chain Why do we Always talk about DNA going in the 5’ to 3’ direction?

  7. Deoxyribonucleotides What is dideoxyadenosine triphosphate (ddATP)? Why are dideoxynucleotides useful in Mol.Bio.?

  8. I hate when DNA is not depicted properly!

  9. Standard 4 exon gene -Where is the polyA tail in the gene above? -Draw a 4 exon gene where exon 4 is all 3’UTR
