Document Summary

There are many species today that contain various different genes. Each species is different and the progeny of the species is also different. Heredity determines that an offspring is similar to the parent but not exactly the same. An egg can determine if an organism is singled or multicellular. All cells store their hereditary information in the same linear chemical code (dna) Living cells are similar to computers storing information. Dna is made from a, t, c, and g. They are put together and encode genetic information. All cells replicate their hereditary information by template polymerization. Monomer of a dna strand is called a nucleotide. Nucleotides contain: sugar (deoxyribose), base (a, t, c, g) and a phosphate group. Bonds between base pairs are weak compared to sugar phosphate bonds. Dna strands can be pulled apart through dna replication without sugar phosphate breaking. All cells transcribe of their hereditary information into the same intermediary form (rna)
