Which of the following molecules are involved in pattern formation during development?
A) cytoplasmic determinants
B) miRNAs
C) cAMP
D) transcription factors

Question

Quizplus · Accepted Answer

Cytoplasmic determinants play a crucial role in creating spatial patterns in developing embryos. These substances distribute unevenly within the egg, and their concentration gradient signals the formation of different cell types during embryogenesis.

Answer: D
 Transcription factors are proteins that bind to specific regions of DNA and control the rate of gene expression. They play a significant role in the differentiation of cells and help determine which genes are turned on or off during development. By regulating gene expression, transcription factors contribute to the establishment of pattern formation during embryogenesis.
