Consider mutations that are deletions or insertions versus a point mutation (change from one nucleotide to another). Which are likely to cause defective or inactive proteins and why?

Solution

Point mutation is the type of mutation whre one nucleotide changes to other nucleotide.. It can form inactive or non-functional protein because the new nucleotide changed can result in the stop codon which can stop the protein synthethis before its original length hence defective..

Similarly insertion of the stop codon can result in the change in reading frame hence truncated protein..
