The Potential Energy for the Interaction Between the Two Atoms

question 49

Multiple Choice

The potential energy for the interaction between the two atoms in a diatomic molecule is U = A/x¹² - B/x⁶, where A and B are constants and x is the interatomic distance. The magnitude of the force of one atom exerts on the other is:

• A) 12A/|x|¹³ - 6B/|x|⁷
• B) -13A/|x|¹³ + 7B/|x|⁷
• C) -11A/|x|¹¹ + 5B/|x|⁵
• D) 72A/|x|¹² - 72B/|x|⁶
• E) A/|x|¹³ - B/|x|⁷

Definitions:

Repressor Protein

A protein that binds to specific DNA sequences and inhibits the expression of a gene by blocking the action of RNA polymerase.

Transcription

The process by which the genetic information in DNA is copied to messenger RNA (mRNA), initiating protein synthesis.

Repressors

Proteins that bind to specific DNA sequences to inhibit the transcription of certain genes, regulating gene expression.

DNA Binding Sites

Specific sequences within a DNA molecule that are recognized and bound by other molecules, such as proteins, to regulate gene expression.
