Functions Common to Eukaryotic Cells All have a DNA – based genetic program Capable of self – replication Capable of expression; DNA mRNA protein One genotype per individual (genomic constancy) ~ 200 phenotypes (differential gene expression) Capable of reproduction (mitotic division) DNA synthesis Karyokinesis Cytokinesis Acquire and utilize energy Glucose-specific transporters. Chemical energy stored as ATP. Capable of mechanical activities Assembly of structures (e.g., ribosomes; microtubules) Movement of solutes (e.g., glucose; amino acids) Movement of organelles (e.g., transport vesicles)

Unformatted text preview: Movement of entire cell (shape change and translocation) Metabolism based on enzymatic (catalytic) degradation / synthesis . Capable of responding to stimuli Signals from the environment chemical; photons; acoustic waves Signals from adjacent cells (paracrine; juxtacrine) Signals from distant cells (endocrine; nerve impulse) Capable of self regulation Response to stress: defense against reactive oxygen species (ROS) Response to damage or mutation: repair or apoptosis Response to cell loss: replacement (normal); regeneration (abnormal)...
