DNA framshifts are caused by ______________ (adding) or _____________ (removing) DNA. Frameshifts are usually not good for an organism and leads to death. Every amino acid brought by _________ before the mutation will be good but after deleting or removing DNA every _______________ made after is incorrect. So an incorrect protein is made.
Other Answer Choices:
deleting
amino acid
tRNA
inserting
