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 nonsense mutation and a missense mutation?
Missense mutation: changes one sense codon to another, resulting in incorporation of amino acid.Nonsense mutation: changes a sense codon into a stop (or nonsense) codon, resulting in premature termination.
If a strand of DNA with the sequence TGA mutated to GCA would it be a silent or missense mutation?
Both a silent and missense mutation is a change in one nucleotide. However, a silent mutation still codes for the same amino acid, but a missense mutation codes for a different amino acid. This means that a silent mutation will have no affect on the resulting protein, but a missense mutation will. Still, it is not guaranteed that a a missense mutation will result in a disfunction of created protein, as long as it is not occurring in the activation site.
Which mutation caused the most drastic change in polypeptide and why?
The mutation that typically causes the most drastic change in a polypeptide is a nonsense mutation, where a single nucleotide change creates a premature stop codon. This results in the truncation of the polypeptide chain, often leading to a nonfunctional protein. In contrast, missense mutations may result in a single amino acid change, and silent mutations do not alter the protein at all. The early termination of translation due to a nonsense mutation can severely impact the protein's structure and function.
What does codon mutation mean?
A codon mutation refers to a change in the sequence of nucleotides in a codon, which is a three-nucleotide segment of DNA or RNA that codes for a specific amino acid. This mutation can lead to various outcomes, such as a silent mutation (no change in the amino acid), a missense mutation (change in one amino acid), or a nonsense mutation (premature stop codon). The effects of codon mutations on protein function can vary significantly, potentially leading to diseases or altered traits.
What mutation causes the DNA replication to stop early?
Nonsense
What are the types of mutations that can occur?
nonsense mutation, missense mutation, frameshift muation, deletion or addition mutation
A mutation that causes antibiotic resistance in bacteria is a what mutation?
Missense mutation Nonsense mutation Frameshift insertion Frameshift deletion All may cause antibiotic resistance in bacteria

Which type of mutation results in abnormal acid sequence?
A point mutation causes a change in the amino acid sequence creating a new type of protein. The mutations are categorized functionally as nonsense, missense and silent mutations.
Which type of mutation resukts in the formation of a protein with one incorrect amino acid?
missense mutation
What results in a regular size protein that is misshapen?
Missense mutation
What could happen to DNA that would cause a change in trait or a new trait to be expressed?
That would be a mutation. There are several types of mutations such as silent, nonsense, missense mutations along with inserstions, deletions and amplifications
What type of mutation causes protein to be synthesized with one incorrect amino acid?
Missense

What type of point mutation is dwarfism?
Dwarfism can be caused by a variety of point mutations, including missense mutations that result in a non-functional protein, nonsense mutations that lead to premature termination of protein synthesis, or frameshift mutations that disrupt the reading frame of the gene.
