Wild type: Protein: Met-Pro-Glu-Pro-Lys-Met DNA: ATG CCC GAA ATG Mutant: Protein: Met-Pro-stop Protein: ATG CCC TAA CCC AAA ATG This mutant can best be called: a) Non-sense b) Silent c) Frameshift d) Mis-sense e) All of the aboveExplanation / Answer
26. Study the nucleotide sequences of wild type and its mutant gene below:
Wild type : GAACCATG Mutant type: GAACAATG
This mutation can best be called:
Answer: d) All of the above
Point mutation is type of mutation where only one or very few nucleotides in a gene sequence is affected.
Substitution is a type of point mutation where one nucleotide is substituted with the other.
Transversion is a type of mutation where a pyrimidine nucleotide (C or T) is substituted by a purine nucleotide (A or G) or vise versa.
27. Study the nucleotide sequences of wild type and its mutant gene below:
Wild type : GAACCATG Mutant type: GAACATG
This mutation can best be called:
Answer: b) Deletion
One nucleotide 'C' is been deleted in the mutant type.
28. Study the nucleotide sequences of wild type and its mutant gene below:
Wild type DNA: ATG CCC GAA CCC AAA ATG
Mutant type DNA: ATG CCC TAA CCC AAA ATG
This mutation can best be called:
Answer: a) Non-sense mutation
Non-sense is a type of mutation that results in premature stop codon.
