how many templates does pcr require?
PCR (Polymerase Chain Reaction) typically requires two templates: one for the forward primer and another for the reverse primer. These templates are usually DNA molecules that flank the region of interest that will be amplified by PCR. In addition, PCR also requires other ingredients such as dNTPs (deoxyribonucleoside triphosphates), Taq polymerase, and buffer solutions to facilitate the amplification process.
An eyelash is stuck behind my upper eyelid. Is it going to stay there forever?
It is unlikely that the eyelash will stay there forever. Usually, the eyelash will naturally fall out or become dislodged and eventually work its way out of your eye. However, if the eyelash is causing discomfort, irritation, or a persistent feeling that something is in your eye, it is best to seek medical attention from an eye specialist. An ophthalmologist or optometrist can examine your eye to confirm the presence of the eyelash and remove it safely, minimizing the risk of injury or infection.

In most cases, the eyelash will have to be removed by a medical professional to prevent any damage or infection to the eye. It is important to seek medical attention promptly to avoid any complications. If left untreated, the eyelash can scratch the cornea or lead to an eye infection. These problems can be very harmful to the eye and may cause long-term damage to your vision. Therefore, it is always better to get medical help and have it removed by an eye specialist rather than waiting for it to go away on its own.
