Answer 1

In PCR, the symbol 'Δ' typically signifies 'change', such as a change in temperature or a genetic mutation known as a delta mutation.

Step-by-step explanation:

In the context of PCR (Polymerase Chain Reaction), which is a technique used in molecular biology, the symbol 'Δ' typically represents 'change' or difference. For example, it is often used to denote a change in temperature between different steps of the PCR cycle or a genetic deletion (delta mutation) when discussing genetic sequences.

Therefore, the correct answer to what the symbol 'Δ' means in a PCR context is 'change' (1).
