ATTENUATION
Blocking or modulation of the excitation light intensity can be accomplished with a series of filters that transmit increasing percentages of the incident light or with an acousto-optic tunable filter (see AOTF).

Attenuation
A mechanism of regulating the level of transcription by interfering with mRNA elongation. Slowed translation through a regulatory region allows formation of a RNA secondary structure that promotes transcription termination.

Attenuation: A form of gene regulation wherein termination of transcription is controlled to regulate overall levels of gene expression.
Avidin: A glycoprotein which binds to biotin with very high affinity (Kd = 10-15).
