Threshold concentration, morphogens, induction, and cell adhesion provide ________ to a developing organism.
A) positional information
B) maternal effect genes
C) homeodomains
D) lineage tracing

Question

Quizplus · Accepted Answer

Threshold concentration, morphogens, induction, and cell adhesion provide positional information to a developing organism, which is critical for the proper patterning of cells and tissues. This information helps determine the location and identity of different cell types, and is essential for the formation of complex structures such as organs and limbs. Maternal effect genes, homeodomains, and lineage tracing are not directly related to the provision of positional information.
