Answer
Mutations occurring during DNA replication in Step A can lead to changes in the genetic material. However, these changes do not necessarily result in new alleles unless they occur in coding regions.
Step 2
Step B: Information is copied from DNA and taken to cytoplasm.

Answer
Mutations in Step B could affect the transcription of genes, but again this would not directly lead to new alleles; instead, it might affect protein synthesis.
Step 3
Step C: Ribosome reads information and assembles protein.

Answer
While mutations can affect the sequence read by the ribosome, changes in protein resulting from this would not create new alleles in the gene itself.
Step 4
Step D: Protein formation is completed.

Answer
Mutations impacting the final protein formation can have functional effects, but they do not change the underlying alleles of the DNA. Therefore, Step D is not where a mutation creates a new allele.
