Which mutation(s) cause the product to be a non-functional protein? a. Nonsense and Missense c. ilent and Nonsense b. Frameshift and Missense
d. Nonsense and Frameshift

The correct answer is - option D. nonsense and frameshift.

Explanation:

If there is a change in the sequence of DNA resulting in premature stop codon mRNA during transcription is known as a nonsense mutation and result in a non-functional protein.

a frame-shift mutation takes place when at least two nucleotides are altered and there are less chances to be changed by two others coding for the same nucleotide. It leads to a non-functional protein.

i thinking chemical change

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!
