Molecular Biologists Undertake a Series of Experiments Designed to Classify

question 92

Multiple Choice

Molecular biologists undertake a series of experiments designed to classify proteins involved in various intracellular signaling pathways.  During one of the experiments, a protein mixture obtained from a cell culture is separated by gel electrophoresis and subsequently transferred to a filter membrane.  Labeled double-stranded DNA probes are then used to detect a specific protein of interest in the sample.  Which of the following proteins is most likely to be detected by this method?

• A)Ras
• B)c-Jun
• C)β1-adrenoreceptor
• D)S-100
• E)Adenylate cyclase

Definitions:

Causality

The principle or relationship between cause and effect, where one event (the cause) directly leads to the outcome (the effect).

Closed-ended Question

A question format that allows for a limited set of specific responses, often used in surveys and polls for easier analysis.

Preferred Screen Size

Preferred screen size is the diagonal measurement of a display that an individual or group finds most desirable or effective for their viewing or interaction needs.

Non-response

The phenomenon where survey participants choose not to or fail to answer certain questions, affecting the accuracy and completeness of data collected.
