A Scientist Has Discovered a New Gene That She Believes

question 49

Multiple Choice

A scientist has discovered a new gene that she believes encodes a transcriptional activator protein. She is trying to determine where this protein binds. Which of the following describes a technique she could use to answer her question?

• A) Chromatin immunoprecipitation to determine the DNA sequences to which the putative transcriptional activator protein binds
• B) RNA interference to determine the RNA sequences to which the putative transcriptional activator protein binds
• C) Crosslinking to determine the interactions the putative transcriptional activator protein has with other proteins
• D) Chromative immunoprecipitation to determine the proteins to which the putative transcriptional activator protein binds
• E) RNA interference combined with crosslinking to determine all DNA and RNA sequences to which the putative transcriptional activator protein binds

Definitions:

Skeletal Muscle

Skeletal muscle is a type of muscle tissue that is attached to bones and helps in voluntary movements by contracting and relaxing.

Locomotion

The ability of an organism to move from one place to another using various mechanisms such as walking, swimming, or flying.

Involuntary Control

The automatic regulation of bodily functions and processes that do not require conscious control, such as breathing and digestion.

Contractility

Refers to the ability of muscle tissue to contract or shorten, generating force.
