Question

Use the table to answer the question below. A mutation causes the following change in DNA. Original DNA sequence: T A C G C A T G G A A T DNA sequence after mutation: T A C G T A T G G A A T Which amino acid substitution will result from this point mutation? Arg is replaced by Met Tyr is replaced by Thr Arg is replaced by His His is replaced by Ala

Answer 1

Answer:Arg is replaced by His

Explanation:

When finding the complementary RNA your first bases would be AUG-CGU-ACC-UUA. For the mutated sequence it would be AUG-CAU-ACC-UUA. Now you use the corona chart and get that the original sequence would’ve been ARGININE and the mutated sequence is HISTIDINE. In case you need the RNA : Leucine-Arginine-Threonine-Leucine MUTATED: Leucine-Histidine-Threonine-Leucine
