Question

The original coding sequence is CAU GGU ACA, which one of the following mutations will not change the protein generated by the original codons? GAU GAU AAC CAC GGC AAC CAC GGC ACG CAU GUU ACA In the following DNA base sequence CTG GAA TGA. In the following DNA base sequence CTG GAA TGA, mutation occurs that changes it to the sequence CTG GAA UGG TGA. What was the type of mutation that occurred? Substitution Deletion Insertion Inversion In the following DNA base sequence GGG CCC AAA. a mutation produced by the insertion of the base A at the start of the whole sequence will produce a protein w hose third amino acid is Gin Arg Ala Gly Questions 15 through 17 assume that the mutated and healthy genes occur within the germ line cells (germ line cells are cells that produce eggs and sperm). If one parent has a single mutant gene but the other parent has two healthy genes, the probability of their children not to have a single mutated gene is 1 out of 4 2 out of 4 3 out of 4

Explanation / Answer

12Q

Answer: In all the mutations, there are no stop codons (UAG/UAA/UGA), so all the mutations will not change the protein encoded by the original codons.
