BlakeA nonsense mutation is a type of mutation that results in the premature termination of protein synthesis, leading to a non-functional protein. A missense mutation, on the other hand, is a mutation that causes a change in one amino acid in the protein sequence, potentially altering its structure and function.
A frameshift mutation is when there is an addition or a deletion of a base pair in the DNA sequence. When the mRNA is then being translated, it is misread because the reading frame is shifted by an extra base, hence frame shift mutation.
A nonsense mutation is when on of the codons is mutated at form a termination codon (UAG, UAA or UGA). It leads to pre-mature termination of the polypeptide.

What are the similarities of a nonsense mutation and a missense mutation?
Both nonsense and missense mutations are point mutations - meaning a single base has been substituted. The difference between the two is that a missense mutation results in an amino acid being replaced with a different amino acid, whereas a nonsense mutation results in a premature stop codon.
What is the Difference between a mutant and mutation?
A mutagen is a substance that CAUSES a mutation. Essentially, mutagens are the cause, mutations are the effect. Simple as that :)
What will happen if there was a change in the base pair sequence?
A change in the base pair sequence, known as a mutation, can lead to changes in the protein produced by the affected gene. This can result in altered gene function, potentially leading to genetic disorders or diseases. The impact of the mutation can vary depending on its location and the specific changes to the DNA sequence.
What is the difference between Sense and Nonsense?
Sense refers to something that is logical, reasonable, or meaningful, while nonsense refers to something that is illogical, irrational, or meaningless. Sense follows a coherent and rational thought process, while nonsense lacks coherence and logic.
What is the difference between helpful and harmful mutation?
a beneficial mutation in an animal, plant, cell or bacteria will allow it to have a better chance of survival and allow it to continue passing on its DNA in its offspring. a harmful mutation does the exact opposite it hinders the animals survival and will eventually lead it's species to extinction.
