Name:___________________________________Date:___________Period:_____ Mutations Exit Worksheet Identify and label the chromosomal mutations for each picture. Word Bank: Inversion, Insertion, Deletion, Duplication, Translocation , Duplicati : Inversion Deleti Insertion Translocatio Looking at the diagram of point mutations, identify each type of point mutation and circle the frameshift mutations. Word Bank: Insertion, deletion, substitution. substitution Insertion deletion Recall that every three letters of DNA (codon) is read to code for one amino acid. If a mutation occurs, is it possible for the protein to be unaffected? Explain your answer. It is possible for a protein to be unaffected since some codons code for the same amino acid. Compare gene mutations and chromosomal mutations. Gene mutations occur change the nucleotide sequence whereas a chromosomal mutation involves changes to the chromosome. What type of mutation do you think would be more severe, a gene mutation or a chromosome mutation? Explain your answer. Since chromosomal mutation involve large amount of DNA it is more likely for that type of mutation to be more severe when compared to a gene mutation that can affect single nucleotide and possibly have not effect on the protein Describe how nondisjunction occurs. when chromosome fail to properly sepertate during mitosis Nondisjunction is a chromosomal mutation that occur when chromosome fail to properly separate during meiosis. The result is having an extra or missing chromosome in a gamete cell. What technique(s) do you think could be used to determine if a fetus is affected by a genetic disorder? Amniocentesis and Chorionic Villi Sampling (CVS) are types of prenatal testing that extract cells to be used for creating a karyotype to help diagnose genetic disorders.
