A Eukaryotic Gene Is Observed to Make Multiple Forms of a Protein.How

question 31

Multiple Choice

A eukaryotic gene is observed to make multiple forms of a protein.How can one eukaryotic gene produce multiple products in the same cell?

• A)Alternative splicing sites can lead to the production of two different mature mRNAs from the same gene,resulting in slightly different proteins.
• B)Epigenetic changes can change the sequence of amino acids in a protein.
• C)Translation rates can affect the length of the polypeptide made from the same mRNA.
• D)Silencer genetic elements can cause early termination of transcription,leading to the production of multiple mature mRNAs from the same gene.
• E)One gene equals one protein,so this observation must be incorrect.

Definitions:

Random Assignment

A technique for assigning individuals to different groups in an experiment using randomization, to ensure that every participant has an equal chance of being placed in any group.

Cause-effect Inferences

Logical deductions that suggest a relationship where one event (the cause) leads to the occurrence of another event (the effect).

External Validity

The extent to which research findings can be generalized to settings or groups outside the study.

Confounding Variables

External factors that can influence both the dependent and independent variables, potentially biasing the results of a study.
