Front

What is the wavelength of light in a material with an index of refraction, n?

Back

Front

What must be true for a Gaussian surface through which the net flux is zero?

Back

The net charge enclosed by the surface is zero (II only).

Front

What is allosteric control in enzyme activity?

Back

Allosteric control refers to the regulation of an enzyme's activity through the binding of a molecule at a site other than the active site, causing a conformational change.

Front

Where does prokaryotic transcription occur?

Back

Prokaryotic transcription occurs in the cytoplasm.

Front

Where does eukaryotic transcription occur?

Back

Eukaryotic transcription occurs in the nucleus.

Front

What happens to resistance if the cross-sectional area of a wire decreases?

Back

The resistance of the wire increases.

Front

What is the relationship between wavelength and index of refraction?

Back

The wavelength of light decreases as it enters a medium with a higher index of refraction.

Front

What is the definition of competitive inhibition in enzymes?

Back

Competitive inhibition occurs when a molecule similar to the substrate competes for binding at the active site of an enzyme.

Front

What is the role of RNA polymerase in transcription?

Back

RNA polymerase is the enzyme responsible for synthesizing RNA from a DNA template during transcription.

Front

What is the difference between introns and exons?

Back

Introns are non-coding sequences removed during RNA processing, while exons are coding sequences that remain in the final mRNA.
