Worked Solution & Example Answer:The steps involved in DNA replication and protein production are summarised below - HSC - SSCE Biology - Question 15 - 2002 - Paper 1
Step 1
Step A: DNA is copied and each new cell gets a full copy.
Answer
A mutation in this step could affect the replication of the DNA itself, leading to changes in the genetic material. However, since this affects the copying of the DNA rather than the expression of traits, it may not directly lead to an immediate new allele formation.
Step 2
Step B: Information is copied from DNA and taken to cytoplasm.
Answer
If a mutation occurs during this transcription process, it could change the RNA constructed from the DNA template. This could lead to a different protein being synthesized, which may result in the formation of a new allele.
Step 3
Step C: Ribosome reads information and assembles protein.
Answer
A mutation here could lead to a change in the sequence of amino acids in the protein being formed. While this could potentially create variations of a protein, it does not guarantee the formation of a new allele since it would depend on whether the change affects the gene's expression.
