Document Summary
Describe the basic structure of dna and explain how it relates to dna replication. Describe the basic concepts of heredity that are found in all sexually reproducing organisms, including humans. Genetics is the study of how traits are transmitted from one generation to the next. Prokaryotic cells are single-celled organisms, represented today by bacteria and blue-green algae. Eukaryotic cells are found in all multicellular organisms: they consist of organelles within a cell membrane. Organelles include the nucleus: surrounded by a nuclear membrane which possess two acids that contain the genetic information that controls the cell"s functions (dna) and (rna). Cytoplasm: a gel like fluid that surrounds the nucleus and contains the other organelles. Two types of cells are gametes: reproductive cells (eggs and sperm in animals) developed from precursor cells in ovaries and testes. And somatic cells: basically, all the cells in the body except those involved with reproduction.
