science (genertics,newtons)

• dna is made up of

  adenine = thymine, cytosine = guanine
• punnet squares

  squares to determine what gene will show (genotype=allelle, phentype=characteristics)
• MItosis

  body cells, produce 2 daughter cell. found in somatic cells.involved in growth and repair
• meiosis

  sex cells (gamtes),produces the reproductive cells in organisms
• mutations

  deletion mutation (removed) subsituation (swoped) insertion (added)
• why mutation 


  by pure chance due to ultravoilet radiation,exposer to chemicals.result in errors in cell
• DNA replication 


  enzymes(speed up,brakedown) helicase(unzip the 2 strands)polymerase(replicates new strand)
