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 a point mutation. This type of mutation involves a change in a single nucleotide within the DNA sequence.
The substituted nucleotide has the same directions as the original nucleotide.
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).
This is a substitution mutation where the nucleotide "c" is replaced with "g" at the beginning of the sequence.
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.
thymine....uracil is its substitution.

Substitution
The substituted nucleotide has the same directions as the original nucleotide.
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.
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.

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.
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.
