Presentation Transcript

  1. DNA - RNA - protein - traits • replication • transcription • translation • triplet code • codon/anticodon • mRNA - t RNA - r RNA

  2. polymer • nucleotides • nitrogen bases - order = code • gene

  3. example proteins/functions • enzymes - lactase, polymerase, helicase • hormones - estrogen and testosterone • transport proteins - hemoglobin, ion pumps • structural proteins - collagen, elastin, melanin • antibodies - anti Rh Proteins give us our traits!

  4. mutations - mutagens • asbestos • cigarette tars • radiation • heat - breaks bonds • mutation - wrong sequence of bases - wrong amino acid - wrong protein • Many mutations still bet the amino acid right and have no resulting problem. • Some mutations can be lethal. Some mutations can be helpful. • The earlier the mutation in development, the more serious.

  5. DNA analysis shows relatedness • identification • paternity • More similarities mean more relationship.

  6. variation of genes leads to variation in appearance • genotype • phenotype • homozygous • heterozygous

  7. monohybrid cross complete dominance incomplete dominance co-dominance

  8. sex-linked traits Why do they show up more often in males?

  9. hemophilia muscular dystrophy
