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.
What codes for the same silent point mutation?
A silent point mutation is a change in a DNA sequence that does not alter the amino acid sequence of the resulting protein. This often occurs due to the redundancy of the genetic code, where multiple codons can code for the same amino acid. For instance, both GAA and GAG codons code for glutamic acid, so a mutation from GAA to GAG would be a silent mutation. Thus, any codon that codes for the same amino acid as the original codon can be considered as coding for the same silent point mutation.
What change to this sequence would indicate a silent mutation?
A silent mutation occurs when a change in the DNA sequence does not alter the amino acid sequence of the resulting protein. This can happen through a substitution of a nucleotide that still codes for the same amino acid due to the redundancy of the genetic code. For example, if the original sequence is "GAA" (which codes for glutamic acid) and it changes to "GAG," this would represent a silent mutation since both codons code for the same amino acid. Thus, the change in the sequence that doesn't affect the protein's amino acid sequence indicates a silent mutation.
Which type of mutation will probably have a larger effect A point mutation or a frameshift?
Both types of mutation have the potential to cause a large effect.In general, a frameshift mutation is more likely to cause a large effect. This is because it shifts the 'reading frame' - so that all of the subsequent codons (groupings of 3 bases that are read to determine which amino acid will be added) will be changed.A point mutation is when a single base is replaced. This can either result in the same amino acid being added to the protein being synthesised (a silent mutation), a different amino acid being added (a missense mutation) or in a STOP codon (a nonsense mutation).If a point mutation causes a premature STOP codon - this is quite likely to have a large effect on the protein.
Why is point mutation dangerous?
A frame shift mutation destroys the correct sequence of amino acids from the point of the mutation. The protein produced by a frame shift mutation would more than likely be nonfunctional.

Why is a silent mutation called silent?
a mutation that does not affect protein production.

A point mutation occurs in a sex cell of an adult rabbit. The gene affected by the mutation is responsible for proteins that build heart muscles. what describes the most likely effect of this mutation?
The point mutation in the sex cell of the rabbit could lead to a change in the amino acid sequence of the protein responsible for building heart muscles. If this mutation alters the protein's structure or function, it could result in compromised heart muscle development or function in the offspring. However, if the mutation is silent or does not significantly affect protein function, the offspring may not exhibit any noticeable heart issues. Overall, the most likely effect would depend on the specific nature of the mutation and its impact on protein function.
Can a frameshift mutation be a silnt mutation?
A frameshift mutation completely changes the genetic code from the point of the mutation, so the protein made as a result of the mutation would have the incorrect structure and would not function as it should.
Which mutation would not change the remainder of the reading frame of a gene sequence that follows the mutation?
A silent mutation, where a nucleotide substitution results in a codon that codes for the same amino acid, would not change the remainder of the reading frame of a gene sequence. This is because the amino acid sequence produced by the altered codon remains the same.
Would a point mutation or a frame shift mutation more likely produce a neutral mutation?
A point shift mutation is more likely to produce a neutral reaction. This is because it involves a change in one nucleotide. A frame shift mutation is more deleterious because it involves the insertion or deletion of multiple base pairs within a gene's coding sequence.
What would most likely cause a new genetic defect to appear in a gene pool?
Mutation .
Which type of point mutation would be insignificant to the organism?
A silent mutation is typically insignificant to the organism. This type of point mutation occurs when a change in the DNA sequence does not alter the amino acid sequence of the resulting protein, often due to the redundancy in the genetic code. As a result, the protein's function remains unchanged, and the organism is usually unaffected by this mutation.
