THE DGR AN represents deletion mutation
THE RED ANA TRA N represents insertion mutation
THE FOX WTS RED represents substitution mutation
Explanation:
Mutation is a change in the nucleotide sequence of a gene. It can be of different types depending on how it occurs. A deletion mutation is that which involves the removal of one or more nucleotide base from the sequence.
An insertion mutation is the addition of one or more nucleotide bases to the sequence.
A substitution mutation is the replacement of one or more nucleotide base in a sequence.
The original sentences were:
1. THE RED ANT RAN
2. THE FOX WAS RED
3. THE DOG RAN
The three sentences that mutated/changed are:
1. THE DGR AN- in this sentence, letter O which represents one base is missing due to removal, making the original sentence (THE DOG RAN) alterated. Hence, this represents an example of deletion mutation.
2. THE RED ANA TRA N - in this case, Letter A has been added in between N and T. This makes the original sentence (THE RED ANT RAN) altered. Since addition of letter (base) occurred, this represents an example of insertion mutation.
3. THE FOX WTS RED - In this case, letter A in "WAS" was replaced by T, making the original sentence (THE FOX WAS RED) altered. Since a replacement of letter (base) is the case here, it represents an example of substitution mutation.
