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 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.

Will the protein coded by the mutated strand of DNA function differently from the original strand?
It depends on the particular mutation. Some are "silent" which means the substitution of a base actually codes for the same amino acid as the previous. In this case, the sequence and function of the polypeptide is exactly the same. If the mutation is a nonsense or missense mutation however, then the structure and function of the protein is indeed affected. A nonsense mutation results in a codon becoming a "stop" codon, thereby terminating the polypeptide prematurely. Such proteins are nonfunctional. Missense mutations result in the change in sequence of amino acids; one amino acid takes the place of another due to the changed codon. These proteins can also be non-functional, but sometimes they can function, albeit less efficiently.

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.

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
