Respuesta :
deletion i checked. when the question pops up just chose it and it will be right.
Answer:
Deletion.
Explanation:
Frameshift mutations are those mutations that lead to change in translation reading frame that codes for a particular amino acid sequence. It causes change in entire amino acid sequence from where mutation starts.
Frameshift mutations can be caused by either insertion of nucleotides (insertion) or by deletion of nucleotides (deletion). The letters in given sentence represents codons (as group of three nucleotides) and the sequence denotes a translational reading frame.
The change in sequence represents deletion mutations as many of the letters are deleted in altered sequence, due to which entire reading frame is changed.
Thus, the correct answer is 'deletion.'
