SyBr Green and SyBr Gold Were Developed Because

Question

SyBr green and SyBr gold were developed because
A) ethidium bromide is not sensitive enough for modern research
B) they allow faster electrophoretic separations of DNA
C) they fluoresce with RNA as well as DNA, while ethidium bromide does not
D) ethidium bromide is carcinogenic

Accepted Answer

SyBr green and SyBr gold were developed as alternatives to ethidium bromide because ethidium bromide is a known carcinogen, posing a risk to researchers who use it. SyBr green and SyBr gold are both non-carcinogenic and offer comparable sensitivity and detection capabilities to ethidium bromide.
