When Laser Tweezers are Used, the Laser Beam Can Trap

Question

When laser tweezers are used, the laser beam can trap
A) an isolated single-copy genome in a capillary tube.
B) a single microbial cell in a capillary tube.
C) a single microbial colony on a plate.
D) multiple cells of the same type on a plate.

Accepted Answer

Laser tweezers are commonly used for trapping and manipulating single cells, like microbial cells, in a capillary tube. This allows for precise handling and control of individual cells. While laser tweezers can also be used to manipulate other biological materials, like isolated single-copy genomes, the most common application is for single-cell manipulation. Laser tweezers are not typically used for trapping whole colonies or multiple cells on a plate.
