Question
Which of the following is NOT a method of communication between cells?
a) Transcription factors are secreted from one cell and taken up by the target cell, where they translocate to the nucleus to differentially regulate gene expression
b) Cell surface molecules on adjacent cells interact and initiate a signal transduction process that influences cellular behaviour and gene expression
c) Cells form gap junctions with adjacent cells, allow passage of small molecules directly via cytoplasmic bridges
d) Cells secrete proteins and small hydrophilic molecules, which interact with cell surface receptors on target cells and initiate a signal transduction cascade that influences cellular behaviour and gene expression.
e) All of the above are valid mechanisms
Explanation / Answer
a) Transcription factors are secreted from one cell and taken up by the target cell, where they translocate to the nucleus to differentially regulate gene expression
