Document Summary
Living matter utilizes energy to survive and create offspring. Life-forms can reproduce, and carry out processes by which they can grow and live. Cells: the smallest unit that have the properties of life and all organisms are composed of one or more of them. Within these cells, the ability of life to reproduce and self-regulate is based on the interaction between compounds known as nucleic acids and proteins. Dna is one form of nucleic acid. It carries the genetic information of all organisms. Primary role of dna is to contribute the information required for production to regulate chemical reactions in cells. Rna is another form of nucleic acid. It carries out the coded instructions given by dna. All recipes for every possible chemical reaction of the organism are stored on the dna molecules within the cell. Every time a cell divides, the library" is duplicated.
