What kind of mutation results from substitution from one nitrogen base to another?
A substitution mutation occurs when one nitrogen base in the DNA sequence is replaced by another. This can lead to three possible outcomes: it may result in a silent mutation (no change in the amino acid), a missense mutation (a different amino acid is produced), or a nonsense mutation (a premature stop codon is introduced). The specific effect depends on the location and nature of the substitution within the genetic code.

Mutation is in tag ctt ggc at?
The original DNA sequence is AGC CCG TA. Inserting the mutation yields AGC CTT GGC AT. This mutation results in a substitution of a single nucleotide in the original sequence.
How does a delation mutation differ from a substitution mutation?
A deletion mutation involves the removal of one or more nucleotide bases from a DNA sequence, which can lead to a shift in the reading frame and potentially alter the entire downstream protein sequence. In contrast, a substitution mutation replaces one nucleotide with another, which may change a single amino acid in the protein or have no effect at all if it occurs in a non-coding region or results in a synonymous codon. While deletions often have more drastic effects on the protein's function, substitutions can range from benign to harmful depending on the specific change.
What type of mutation results in abnormal amino acids sequence?
A missense mutation results in an abnormal amino acid sequence. This type of mutation occurs when a single nucleotide change in the DNA sequence leads to the substitution of one amino acid for another in the protein product. Depending on the specific change, this can impact the protein's function and stability. Other types of mutations, such as nonsense or frameshift mutations, can also disrupt the amino acid sequence but in different ways.
When a substitution of a nucleotide results in the early additon of STOP codon to the amino acids chain what kind of mutaion is it.?
When a substitution of a nucleotide leads to the early addition of a STOP codon in the amino acid chain, it is called a nonsense mutation. This type of mutation results in a premature termination of protein synthesis, potentially leading to a truncated and often nonfunctional protein. Nonsense mutations can have significant effects on the organism, depending on the role of the affected protein.
Sequence would indicate a missense mutation?
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.

What happens during a substitution mutation and how does it impact the genetic code?
During a substitution mutation, a single nucleotide in the DNA sequence is replaced with a different nucleotide. This can lead to a change in the amino acid that is coded for, potentially altering the protein that is produced. The impact on the genetic code depends on whether the substitution results in a silent mutation (no change in the amino acid) or a missense mutation (change in the amino acid), which can affect the function of the protein.
Sicklecell anemia is caused when a mutation results in the replacement of glutamate with valine. Which type of mutation is observed here?
The mutation that results in the replacement of glutamate with valine in sickle cell anemia is a missense mutation. This type of mutation occurs when a single nucleotide change in the DNA sequence leads to the substitution of one amino acid for another in the resulting protein. In this case, the specific change involves the codon for glutamic acid being altered to code for valine, which affects the hemoglobin structure and function.
When is a single base substitution mutation least likely to be deleterious?
A single base substitution mutation is least likely to be deleterious when it occurs in a non-coding region of DNA, such as in an intron or in a region with no functional significance. Additionally, if the mutation results in a silent or synonymous change in the amino acid sequence, it may not have a noticeable effect on the protein's function.
Which type of mutation results in the formation of a protein with one incorrect amino acid-?
A point mutation, specifically a missense mutation, is responsible for the formation of a protein with one incorrect amino acid. This type of mutation involves a single nucleotide change in the DNA sequence, leading to the substitution of one amino acid in the protein.

Nonsense mutations can have significant effects on the organism, depending on the role of the affected protein.
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.
Sequence would indicate a missense mutation?
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.

Identifying these changes can provide insights into the mutation's potential effects on health or disease.
What mutation stops translation of the mRNA?
The type of mutation that stops the translation of a protein is a nonsense mutation. This occurs when a base substitution (point mutation) results in a STOP codon and thus stops translation of the sequence into a protein.
What is transversion mutation?
A transversion mutation is a type of point mutation where a purine base is substituted for a pyrimidine, or vice versa. This type of mutation results in a change in the base pair from a double-ring structure to a single-ring structure, potentially causing changes in the amino acid sequence during protein synthesis.
