genetic Mutations

Match each example to a type of mutation. Match each type of mutation with the example given for it. Substitution ACA GTT --> ACT GTT Deletion ACA GTT --> ACG TT Insertion ACA GTT --> ACA GAT T Move each type of mutation to the category where it belongs. Point Mutation substitution Frameshift Mutation insertion deletion Fill in the blanks with the term(s) that makes the statement correct. 1. A gene mutation is a change in one or more bases in DNA.2. Mutations are caused by mutagens like UV light or chemicals A point mutation is when 1 nucleotide base in DNA is changed.4. A deletionmutation is when a nucleotide base is lost.5. An insertion mutation is when an extra nucleotide base is inserted.6. Both deletion and insertion mutations may cause what is called a frame-shift because the codon pairs change as do the amino acid sequences.7. A substitution mutation occurs when one nucleotide base is substituted for another. If the original DNA is ATAACGCCTATT... then the number of codons is 3 4 11 12 Using the following DNA sequence, determine the type of mutation that has occurred with the new sequence. T A C A C C T T G G C G A C G A C T New Sequence Type of mutation T A C A T C T T G G C G A C G A C T Substitution T A C G A C C T T G G C G A C G A C T Insertion T A C A C C T T G G G A C G A C T Deletion Consider a portion of a DNA strand with the following sequence of bases: CATATGGTCTGTSuppose the bases were not transcribed correctly and the resulting mRNA read: GUAUCACACAWhat type of gene mutation does the represent? Does it change the assembly of the polypeptide? (You need to consult a codon chart on Google Classroom)
