Answer: Increased transcription by loosening chromatin. Acetylated histones create open chromatin structure that promotes gene transcription.
Answer: It provides signals that activate or repress gene expression pathways. Cell signaling coordinates differentiation by transmitting developmental instructions.
Answer: Division producing unequal cell contents, yielding daughter cells with different fates. Unequal distribution of cellular components creates daughters with distinct developmental potential.
Answer: Rapid electrical signaling and communication via synapses. Neurons develop specialized structures for transmitting electrical signals between cells.
Answer: Contraction through organized actin and myosin filaments. These cells develop specialized contractile machinery for force generation and movement.
Answer: Moving substances along surfaces using coordinated cilia beating. Coordinated cilia create directional fluid flow across epithelial surfaces.
Answer: Specialization for lipid metabolism and detoxification reactions. Smooth ER abundance reflects the cell's role in processing lipids and toxins.
Answer: Specialization for high ATP demand through increased aerobic respiration. More mitochondria provide the ATP needed for energy-intensive cellular functions.
Answer: gene expression. Gene expression patterns change while the underlying DNA sequence remains constant.
Answer: Different cell types transcribe and translate different subsets of genes. This process explains how identical genomes produce diverse cell types.
Answer: Determination followed by differentiation. Cells first commit to a fate, then develop the structures for that function.
Answer: A chemical signal that influences cell fate, often in a concentration gradient. Concentration differences of these molecules provide positional information to cells.
Answer: A DNA sequence where RNA polymerase binds to begin transcription. This is the initiation site where transcription machinery assembles and starts RNA synthesis.
Answer: A DNA region where regulators bind to increase transcription of a gene. These regulatory sequences boost gene expression when bound by activator proteins.
Answer: A regulatory protein that binds DNA and controls transcription of genes. These proteins determine which genes are transcribed by binding to DNA sequences.
Answer: A stem cell that produces only one differentiated cell type. The most limited stem cells, producing only one type of specialized cell.
Answer: A cell that can form multiple related cell types within one tissue lineage. These cells are restricted to producing cells within their specific tissue type.
Answer: Programmed cell death that shapes tissues and removes unneeded cells. This controlled cell death sculpts developing tissues and eliminates excess cells.
Answer: Gene expression leading to protein synthesis. Gene transcription and translation create the specialized proteins defining cell function.
Answer: They express different sets of proteins that build different cellular structures. Unique protein profiles determine cellular architecture and organelle composition.
Answer: Formation of distinct tissues such as muscle, nerve, and epithelium. Different tissues arise from cells specializing for distinct physiological functions.
Answer: Changing DNA packing to make genes more or less accessible for transcription. This process controls gene accessibility by modifying DNA-protein interactions.
Answer: Increased transcription by loosening chromatin. Acetylated histones create open chromatin structure that promotes gene transcription.
Answer: Specialized cells form tissues and organs with specific physiological roles. Cellular specialization enables tissues to perform complex physiological functions efficiently.
Answer: Reduced transcription (gene silencing). Methylated DNA regions are typically condensed and transcriptionally inactive.
Answer: A heritable change in gene activity without changing the DNA sequence. These modifications alter gene expression states without mutating the underlying DNA.
Answer: Determination commits fate; differentiation produces specialized structure and function. Determination sets the fate while differentiation executes the structural changes.
Answer: A commitment step where a cell becomes biased toward a specific lineage. This restricts cell potential and establishes the pathway toward a specific cell type.
Answer: The sequence of cell divisions and fate choices leading to a specific cell type. This traces the developmental path from stem cell to final specialized cell type.
Answer: A process where one group of cells signals another to differentiate. This cell-cell communication mechanism directs neighboring cells toward specific fates.
