1) The WILDTYPE DNA/gene has the base sequence:

5’GTACTGCAT3’ (the antisense strand of the gene is shown)

The gene has undergone a mutation. The mutant DNA/gene has the base sequence:

5’GTACTCCAT3’ (the mutation is in BOLD)

based on this information, answer the following

1a)What is the base sequence of mutant mRNA? Label the ends of the mRNA

1b) this mutation is most likely to be caused by:

a. soot b. analogues c. X-Ray d. RNA polymerase e. ribosome (pick one)

1c). What is the amino acid sequence specified by the mRNA transcribed from the mutant DNA? What do we call this type of mutation? Is it likely to change the protein more drastically than a mutation caused by removing a base from the gene?

1d). (not related to the information given above) which of the following is unlikely treat bacterial infections

a. animal virus b. phages c. RNA polymerase inhibitors d. repressors e. ribosome inhibitors (pick one)

1e). (not related to information given above) can DNA replication result in genetic change. explain
