Document Summary

2. 1b the fundamental unit of life is the cell: cell theory, all organisms are composed of one or more cells, prokaryotes are composed of a single cell. In unicellular organisms, the one cell is functionally independent, capable of life activities. In more complex cells, life activites are divided among specialized cells. Dna & rna contain the info required to manufacture a vast array of biological molecules: new cells can arise only from the division of pre-existing cells. Info in dna is copied onto molecules of rna, which then directs the production of protein molecules. Even simple cells contain thousands of proteins coded from a dna sequence: enzymes are required to catalyze the replication of dna, the transcription of dna into rna & finally the translation of rna into a protein. Info is preserved from generation to generation by the ability of. Dna to direct its own replication so offspring receive the same molecular instructions their parents have.
