Final answer:
In chemistry, the time you need to wait before removing and inspecting the primer depends on the specific protocol being followed. It can range from 30 seconds to 1 minute.
Step-by-step explanation:
In chemistry, when the Traffic Light System for Wet Sampling Determination (TWD) is GREEN or YELLOW, you should wait for a specific duration before removing and inspecting the primer.
The time you need to wait depends on the specific protocol or guidelines being followed. One example is the PCR (polymerase chain reaction) cycling program, where a green or yellow signal may indicate that the reaction has reached the extension or annealing step.
In this case, you would typically wait for about 30 seconds to 1 minute before removing the primer for inspection. However, it is crucial to consult the specific instructions or guidelines provided for the particular protocol being followed, as wait times can vary depending on the method or system used.
