Answer 1

Answer:

Frameshift mutation

Explanation:

Frameshift mutation is a form of mutation that results from deletion or insertion of nucleotide in a DNA sequence in such a way that the way the DNA sequence is read becomes shifted.

In this case, the nucleotide 'f' was inserted just before the second codon in the sequence while the last nucleotide 'e' at the end of the sequence was deleted. These shifts the entire way in which the sequence is read in the mutant copy of the DNA.

Answer 2

Answer:

Insertion.

Explanation:

Insertion mutation:

In insertion mutation, the sequence of DNA permanently change by addition of one or more nucleotides. If mutiple of three nucleotides inserted into DNA sequence then there will be non-frameshift mutation occurs but if multiple of one or two nucleotides inserted into DNA sequence then it will be frameshift mutation.

Above scenario is a classical example of frameshift mutation by addition of one nucleotide.

The actual sequence is: The big red fly had one eye.

Now the addition of one nucleotide which shown in bold letter.

(wild type): The big red fly had one eye.

(mutant):     The fbi gre dfl yha don eey.

So, insertion of one nucleotide (f) can lead to frameshift mutation.
