Transcript of "Dna mutations"

  1. 1. DNA Mutations <br />
  2. 2. Types Of Mutations <br />Substitution <br />Insertion<br />Deletion<br />Frame shift<br />
  3. 3. Substitution<br />A substitution is a mutation that exchanges one base for another (i.e. , a change in a single “chemical letter” such as switching an A to G. <br />For example:<br />CTGGAG<br />CTGGGG<br />
  4. 4. Insertion<br />Insertions are mutations in which extra base pairs are inserted into a new place in the DNA.<br />CTGGAG<br />CTGGCCTAG<br />
  5. 5. Deletion<br />Deletions are mutations in which a section of DNA is lost or deleted. <br />CTGGAG<br />CTAG<br />
  6. 6. Frameshift<br />In a frameshift mutation one or mare bases or inserted, deleted the equivalent of adding or removing letters in the sentence. But because our cells read our DNA in three letter words, adding or removing one letter changes each subsequent word. This type of mutation can make the DNA sequence meaningless .<br />For example: <br /> Original= the fat cat ate the wee rat<br />Frameshift= the fat caatet hew eerat. <br />
  7. 7. Sample Question<br />1. THE CAT SAW THE FAT RAT<br />2. THE CAT SAW THE RAT<br /> The change in Statement 1 to form Statement 2 is most similar to what type ofmutation?<br />Insertion<br />Deletion<br /> Substitution<br />Frameshift<br />
  8. 8. Sample Question<br />The correct answer is G.<br />Because the sentence is missing the word fat which occurs in deletion as it is the removal of a section of DNA. <br />
  9. 9. Sample Question<br />
