In the construction of an expression vector, a signal sequence
A) allows for the expression of a gene in a particular tissue only.
B) allows the expression of a gene to be turned on or off.

Question

Quizplus · Accepted Answer

A signal sequence directs the protein product to the appropriate location within the cell or organism. It ensures that the protein is expressed in the correct location, such as a specific organelle or extracellular space, and that it functions properly within that environment.

Note: Choices A, B, D, and E are not accurate descriptions of a signal sequence.
