Question

After using a chemical mutagen to generate mutations in a DNA sequence, scientists noted a mutation from C to T at the 10th position within the coding region of a gene. This mutation led to a change of proline into serine at the fourth position in the resulting peptde. Using this information and the sequences listed below, select all the types of mutations that occurred missense Original Mutant | | sequence ATG CGT-ACT-CCT-TAA base substitution mRNA AUG-CGU-ACU-CCU-UAA AUG-CGU-ACU-UCU-UAA sequence induced Peptide Met-Arg-Thr-Pro-STOP Met-Arg-Thr-Ser-STOP sequence O Prevous G20 up & View Solution Nan € Exit Check Answer about us carcers privacy policy erms of use contact us MacBook Air F3 00 F4 F5 F6 F8

Explanation / Answer

ANSWER

Missense - Since one nucleotide change produced a different amino acid altogether
Base Substitution - since a base was swapped for another (not the same as insertion or deletion)
Induced - since a chemical mutagen was employed to trigger this
Transition - since one pyrimidine switched to another pyrimidine, and no cross-changes were seen, like Pu to Py or Py to Pu
