What do you use to write on transparency?
You can use permanent markers or wet-erase markers to write on transparencies. Avoid using dry-erase markers as they can easily smudge or rub off.
Difference between overhead and dry erase markers?
The ink used in dry-erase markers is almost identical to that used in permanent markers. It is comprised of colored pigments, a chemical solvent (like alcohol) and a polymer or "release agent." The type of polymer used marks the main difference between dry-erase and permanent markers. Unlike permanent markers, which use acrylic polymers to make the pigment stick to surfaces, dry-erase markers use an oily silicone polymer. The ink's slippery consistency prevents the colored pigment from coming in direct contact with the surface so it can easily be wiped off.
Are permanent markers really permanent on an dry erase board?
Permanent markers are not designed to be used on a dry erase board as they are not easily erasable. They can leave stains on the board and are difficult to remove. It is best to use dry erase markers on a dry erase board.
Can you write on plastic?
Yes, plastic surfaces can be written on with permanent markers or special markers designed for writing on plastic. It is important to make sure the marker is dry before touching the surface to avoid smudging.
What is the term for genetic markers that turn DNA segments on and off?
The term for genetic markers that turn DNA segments on and off is "epigenetic markers." These markers do not alter the DNA sequence but control gene expression by regulating access to specific regions of DNA.
