Before you know what a nucleotide substitution error is, you have to know what a nucleotide is. A nucleotide holds the DNA strand together and helps make copies. When a Strand is ready to be copied, Let's say one nucleotide reads for G(Guanine), then another nucleotide would be added, which would mean C (Cytosine) would be added. A substitution error would mean that, that instead of Cytosine being added, Thymine, Adenine, Uracil, or Guanine could be added, resulting in a mutation.

If one nucleotide is replaced by another it is called?
If one nucleotide is replaced by another, it is called a point mutation. This type of mutation involves a change in a single nucleotide within the DNA sequence.
Why does not the substitution of nucleotides in the mouse change its phenotype or physical characteristics?
The substituted nucleotide has the same directions as the original nucleotide.
Changes in a DNA sequence caused by substitution of one nucleotide for another?
A substitution mutation occurs when one nucleotide in a DNA sequence is replaced with a different nucleotide. This can lead to a change in the corresponding amino acid in the protein produced from that gene, potentially altering the protein's structure and function. Substitution mutations can be silent (no change in the amino acid), missense (change in one amino acid), or nonsense (premature stop codon).
What type of mutation is actggu to agtggu?
This is a substitution mutation where the nucleotide "c" is replaced with "g" at the beginning of the sequence.
Why doesn't the substitution of nucleotides in the mouse change its physical characteristics?
The substitution of nucleotides in the mouse may not change its physical characteristics because many nucleotide substitutions do not alter the amino acid sequence of proteins. Also, not all changes in DNA lead to changes in phenotype because some mutations may occur in non-coding regions of the genome. Additionally, the phenotype of an organism is the result of a complex interplay of many genes and environmental factors, so the effect of a single nucleotide substitution may be negligible.
In RNA the nucleotide is substituted for?
thymine....uracil is its substitution.

If one nucleotide is replaced by another, it is called a point mutation. This type of mutation involves a change in a single nucleotide within the DNA sequence.
Which mutation occurs when one nucleotide is replaced with another base?
Substitution

How are substitution mutations caused?
Substitution mutations are typically caused by errors during DNA replication, where a wrong nucleotide is incorporated into the DNA sequence. This can also be caused by exposure to mutagens, such as certain chemicals or radiation, which can lead to changes in the DNA nucleotide sequence.
What is a base substitution?
A base substitution is a type of mutation in DNA where one nucleotide is replaced by another. This type of mutation can lead to the substitution of one amino acid in a protein for another, potentially altering the protein's structure and function. Base substitutions can have various effects on an organism, depending on the location and nature of the mutation.

True or false The substitution of one nucleotide for another in the gene never affects the function of the protein?
true
Which mutation occurs when one nucleotide base in replaced with another base?
A point mutation occurs when one nucleotide base is replaced with another base. This can lead to changes in the amino acid sequence during protein synthesis, potentially affecting the protein's function.
The substitution addition or removal of a single nucleotide in DNA is called a what mutation?
The substitution, addition, or removal of a single nucleotide in DNA is called a point mutation. This type of mutation can result in changes to the amino acid sequence of a protein, leading to potential functional consequences.
What are types of point mutation?
The types of point mutations are: base-pair substitution, insertions, deletions, and frameshift mutations. In base-pair substitution, one nucleotide and its corresponding partner are replaced with another pair of nucleotide. In insertion, nucleotide pairs are added to a gene. In deletion, nucleotide pairs are taken out of a gene. Frameshift mutation happens as a result of insertion or deletion when more or less than three (or a multiple of three) nucleotide pairs are added to or taken from a gene.
