Mutation occurs where one DNA nucleotide base is changed in the process of DNA replication. These mutations may or may not cause genetic disorders or other observable changes in the organism, but they play a huge role in evolution, cancer, and immune system development.
One common example of a substitution mutation is a point mutation where one nucleotide base is replaced by another. This can lead to changes in the amino acid sequence of a protein during translation. An example would be a mutation where a Cytosine (C) is substituted for a Thymine (T) in the DNA sequence.
During replication, enzymes called helicases unwind and separate the DNA strands by breaking the hydrogen bonds between the base pairs. This process creates a replication fork where new complementary strands are synthesized.
DNA replication is the second part of inter-phase where the cell makes an exact copy of the DNA in its cell. Please see the answer to the related question below..
DNA replication occurs during the S phase of the cell cycle.
DNA polymerase adds nucleotides to the growing DNA strand at the replication fork during the process of DNA replication.
Mutations
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.

The specific type of mutation resulting from a mistake during DNA replication will depend on the nature of the mistake and the type of nucleotide substitution that occurred. Some possible types of mutations include point mutations (such as a substitution, insertion, or deletion of a single nucleotide), frameshift mutations, or silent mutations.
A cell's DNA is copied during replication.
I can find no reference to a molecule used in "pf" replication. Do you have another term in mind? Please resubmit your question if you do.
Nucleotide pair substitution is a type of mutation where one nucleotide in a DNA sequence is replaced by another nucleotide. This can lead to changes in the protein encoded by the gene, potentially altering its function. Substitutions can be classified as silent (no effect on protein), missense (changes one amino acid), or nonsense (creates a premature stop codon). These mutations can arise from errors during DNA replication or environmental factors.
The difference between between replication and replication is that replication is the series of copies, and repetition is the series of repeats.
dna is that because the structures of what is does. and how it reacts
During replication, enzymes called helicases unwind and separate the DNA strands by breaking the hydrogen bonds between the base pairs. This process creates a replication fork where new complementary strands are synthesized.
because it just is
DNA is made during replication. RNA is made during transcription. Proteins are made during translation.
