Document Summary
Cells go through a very processed cycle. Hereditary information is stored in dna chemical code. All cells store information in this way. All cells proliferate and carry on their information through their replication by template polymerization. Dna is a fixed part of you - what you inherit from parents. Protein is not affected by this reaction. All cells are bounded by a plasma membrane. Plasma membrane - acts as a selective barrier from interior and exterior. Has to be able to communicate with environment. All cells use atp as the energy source. Cells can be broken up into two categories: Used to be their own separate organism. 3 main systems that make up the cytoskeleton: microfilament, microtubules, intermediate filaments . All cells in the body contain the same dna and become specialized due to differential expression of genetic information. Improvement in our ability to describe cell structure. Proteins have intrinsic signals that govern their transport and localization in cells.
