DOG BIT THE CAR DNA and Mutations - Deletion THE DOG BIT THE CAT • Deletion: Delete just one letter (T): THE DOG BIT HEC AT DNA and Mutations-Insertions THE DOG BIT THE CAT • Insertion - Add just one letter (E): THE DOE GBI TTH ECA T Cells have “proof reading” proteins that constantly check the DNA and fix errors, so most are corrected Protein Synthesis- you try it! DNA transcription and translation-... change the genetic code, and be replicated when forming new body cells • In sex cells, can be passed on to offspring • Mutations can be neutral, beneficial, or harmful • ex: Blue eyes – a mutation that occurred 610,000 years ago, can be traced back to one ancestor • what kind of mutation is that? DNA and Mutations – Lets looks at different mutations THE DOG BIT THE CAT DNA and Mutations - Substitution...DNA and Protein Synthesis • Amino acids are linked together in the same order as the codons , creating a protein chain • Just like linking letters to make words, linking amino acids makes proteins Amino Acid Amino Acid Amino Acid DNA and Mutations Mutations are any changes that take place in DNA: • Can be spontaneous or
