Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The original and mutated DNA have been transcribed below. Will the mutated DNA create a different protein from the original?Original:ACU AUGMutated:ACC AUG
A
No because both the original and mutated DNA code for Threonine-Methionine.
B
Yes, because both of them contain different amino acids.
Explanation: 

Detailed explanation-1: -Sometimes, gene variants (also known as mutations) prevent one or more proteins from working properly. By changing a gene’s instructions for making a protein, a variant can cause a protein to malfunction or to not be produced at all.

Detailed explanation-2: -An insertion changes the DNA sequence by adding one or more nucleotides to the gene. As a result, the protein made from the gene may not function properly. A deletion changes the DNA sequence by removing at least one nucleotide in a gene.

Detailed explanation-3: -Genetic mutations are changes to your DNA sequence that happen during cell division when your cells make copies of themselves. Your DNA tells your body how to form and function. Genetic mutations could lead to genetic conditions like cancer, or they could help humans better adapt to their environment over time.

Detailed explanation-4: -Missense Mutation A missense mutation is a DNA change that results in different amino acids being encoded at a particular position in the resulting protein.
