Paraphin [41]

Answer:

Original reading frame=> (ATG)(CGT)(CCA)(TGA)

Altered reading frame => (ATG)(CAC)(GTC)(CAT)(GAG)

Explanation: A frame shift mutation is a type of mutation in which there is addition or deletion of one or more nucleotides in a DNA sequence which results in alterations in the original reading frame of the DNA sequence. In the altered reading frame above two nucleotides were added at positions 4 and 5 thereby changing the subsequent reading frame of the DNA.
