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.

This is a missense mutation because it’s coded for a different amino acid.

∙ 9y agoA missense mutation will use only one or two substitutions to change the material. The silent mutation results with many substitutions over time.

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.
What is a A genetic mutation that does not result in a change in the amino acid sequence of the resulting protein is called?
a silent mutation.
A mutation that occurs at a specific location within a nucleotide sequence is called a?
Point mutation and it can be effective or silent depend upon at the site of codon
Write a sentence using silent mutation missense mutation frameshift mutation non sense mutation deletion dupication inversion transloction gene rearangement?
a silent mutation is one that doesn't affect the overall physiological role or roles of the species, so it has no change or noticeable change in the subject. A missense mutation simply causes one amino acid to change into a different amino acid, it could cause a problem or it could not. A frameshift is when an amino acid is removed. The removal moves all amino acids hereafter over one, which changes the codon sequence of the entire gene. This mutation can be detrimental. A nonsense mutation is usually classified as a premature stop codon. It's a point mutation that can cause a gene to become smaller than it really is. an inversion is the reversal of a gene, which is also very problematic. Translocations are removal of one amino acid, which is then transferred to a separate nonhomologous chromosome. A gene rearrangement is just another name for a duplication, inversion, or deletion. It's not one sentence, but it is a hell of a lot of good information. email for questions: bmalinak@gmail.com
What will happen if there was a change in the base pair sequence?
Changing a base pair on a human chromosome (or any organism's chromosome) can range from no effect to catastrophic. The changing of a base pair -- a mutation -- can either result in a nonsense mutation, a missense mutation, or a silent mutation.A nonsense mutation changes a codon upstream of the normal stop codon into a stop codon, resulting in a truncated protein. Such proteins are non-functional and usually result in a non-viable offspring although some can survive (with serious genetic disorders).A missense mutation is just like a nonsense mutation, except the codon isn't changed into a stop codon and the protein does not terminate early. The only difference between the normal protein and the affected protein is that the affected protein will have one amino acid along the polypeptide chain that is different. The affects of such a change can change the shape of the protein entirely, seen with sickle-cell anemia.A silent mutation has no effect on the protein produced. There are only 20 amino acids, but 43 variations of four bases arranged three at a time (in other words, there are 64 different codons possible). Accordingly, more than one codon can code for the same amino acid. For example, both UAU and UAC code for the amino acid tyrosine. Imagine a point mutation replaced the U in UAU with a C making it UAC. Either way, the amino acid that will be used will be tyrosine, in no way changing the structure of the protein. For that reason, these mutations are "silent" or having no effect.
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.

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
Why is a silent mutation called silent?
a mutation that does not affect protein production.
Describe 4 ways mutation can occur without change its phenotype?
The phenotype will not be affected with silent mutation and synonymous mutation. It also can be mutated in a coding region that changes the amino acid or changes the protein to be folded.

What is point mutation substitution?
When a nitrogen base is substituted for a different one so it may code for a different amino acid. Sometimes substitution still codes for a same amino acid, in which case it becomes a silent mutation, but in other times it may alter the protein entirely.
How might a biologist determine whether a mutation has occurred?
The comparison between the DNA sequence of normal DNA to the mutated DNA will be made. The type of mutation will be revealed during the base sequence.

What is mutation and how many types of mutaion are there?
A mutation is any change in the DNA sequence. This list probably isn't exhaustive, but the types I can think of are: point (one basepair is changed into another) deletion (one or more basepairs is removed) insertion (one or more basepairs is added to the DNA sequence) translocation (a segment of DNA is moved from one region to another) duplication (a region of DNA is... well duplicated... some regions of DNA, particularly repetitive regions are often subject to extensive expansion) If you want to get really technical there are lots of subtypes and terminology used to describe mutations. A point mutation could also be termed a lot of other things, particularly if it is in a stretch of coding DNA (silent, missense, and nonsense mutations) and can be further subdivided by whether it's a change between a purine and a purine (transition mutation), a pyrimidine and pyrimidine (also a transition mutation), or a purine and a pyrimidine (transversion mutation).
