Answer
In Step A, DNA replication occurs, providing a full copy of the genetic material. A mutation here would not lead to the formation of a new allele but rather replicate the existing alleles.

Answer
Step B involves the transcription process where information is copied from DNA. A mutation in this step might affect the RNA but would not necessarily result in a new allele as it deals with transcription rather than direct alteration of DNA.

Answer
Step C refers to translation, where the ribosome synthesizes proteins based on the mRNA sequence. A mutation in the DNA, if it occurs here, could cause a misreading of the genetic code but typically does not directly alter the alleles themselves.

Answer
Step D culminates the protein synthesis process. Although a mutation can affect protein formation, it's the genetic alterations in the previous steps that would ultimately lead to new alleles. Therefore, the mutation leading to a new allele would ideally occur prior to this step.
