FAQ
Q: What is the role of genetics in individual development?
A: Genetics play a crucial role in individual development by directing processes such as cell differentiation, gene expression, and cell proliferation.
Q: What is cell differentiation?
A: Cell differentiation is the process by which a cell changes into a specialized cell type with specific functions.
Q: What are stem cells and what is their role in differentiation?
A: Stem cells are undifferentiated cells that have the ability to differentiate into various cell types, playing a key role in tissue formation and regeneration.
Q: How do external stimuli influence the differentiation of cells?
A: External stimuli and signaling pathways can influence cell differentiation by directing cells to develop into specific types based on the environmental cues they receive.
Q: What mechanisms control cell development and differentiation?
A: Various mechanisms such as genetic regulation, gradients, and signaling pathways are involved in controlling cell development and differentiation.
Q: What are homeotic genes and what is their role in development?
A: Homeotic genes are master regulatory genes that control the body structure and transformations in development by guiding the formation of specific body segments and organs.
