Question

multiple - choice question
what is a frameshift mutation?
the shifting of dna to mrna
the movement of bases out of the original position.
the formation of codons made of four bases
changing the frame of dna and shift it to the ribosome.

Explanation:

A frameshift mutation occurs due to insertions or deletions of nucleotides that are not in multiples of three, shifting the reading - frame of the genetic code. This is equivalent to the movement of bases out of their original position in the normal sequence. The other options do not correctly define a frameshift mutation. Shifting DNA to mRNA is part of transcription, formation of four - base codons is not a frameshift mutation, and changing the frame of DNA and shifting to the ribosome is not the proper definition of frameshift mutation.

Answer:

The movement of bases out of the original position.
