A missense mutation occurs when a single nucleotide change results in the substitution of one amino acid for another in a protein. This type of mutation can alter the protein's function or stability, depending on the specific amino acid change and its location within the protein. Sequence analysis can reveal this mutation by comparing the DNA or mRNA sequence to a reference sequence, where the altered codon corresponds to a different amino acid. Identifying these changes can provide insights into the mutation's potential effects on health or disease.

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 type of mutation would only affect one amino acidwhich type of mutation would only affect one amino acid?
A missense mutation is the type that would only affect one amino acid in a protein sequence. This occurs when a single nucleotide change in the DNA sequence results in the substitution of one amino acid for another in the corresponding protein. This alteration can potentially impact the protein's function, depending on the role of the altered amino acid. Other mutations, like silent or nonsense mutations, do not affect the amino acid sequence in the same way.
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.
What is the point mutation of AGGCGTCCATGA?
A point mutation refers to a change in a single nucleotide in a DNA sequence. In the sequence AGGCGTCCATGA, any alteration of a single base pair would qualify as a point mutation. For example, if the first 'G' were replaced with an 'A', the mutated sequence would be AGGCGTCCATGA → AAGCGTCCATGA.
What kind of mutation is tag ctt ggc at?
The sequence "tag ctt ggc" provided does not represent a specific mutation. A mutation would involve a change in a specific base or bases within a DNA sequence. Without further context or details, it is not possible to determine the type of mutation.

A part of an mRNA has the sequence CCG. which change to this sequence would indicate a missense mutation?
CGG GAA
What One example of a mutation that would not affect an organisms phenotype?
A silent mutation is an example of a mutation that would not affect an organism's phenotype. This type of mutation occurs in a non-coding region of DNA, such as an intron, and does not change the amino acid sequence of the protein produced. Therefore, it has no impact on the organism's outward appearance or characteristics.

What happens if only one amino acid is coded incorrectly?
If only one amino acid is coded incorrectly in a protein sequence, it may result in a missense mutation. This could potentially lead to a change in the structure and function of the protein. The impact of the mutation would depend on the specific amino acid involved and its location within the protein.
What would have a bigger effect on organism an error during transcription or a missense mutation?
IF only you weren't here for apex! you're welcome for making your day!
Which do you suppose would be more harmful A mutation that changed the nucleotide sequence of an mRNA molecule or a mutation that changed the nucleotide sequence of a DNA molecule?
A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.
What is the point mutation of AGGCGTCCATGA?
A point mutation refers to a change in a single nucleotide in a DNA sequence. In the sequence AGGCGTCCATGA, any alteration of a single base pair would qualify as a point mutation. For example, if the first 'G' were replaced with an 'A', the mutated sequence would be AGGCGTCCATGA → AAGCGTCCATGA.
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.
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.
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
