PPT-Chromosomes Gene – segment of DNA that carries instructions for a specific trait

DNA in cells is usually spread out so transcription can take place During cell division chromosomes form Chromosomes are DNA and protein histones coiled into a rod After DNA replicates two .

Genetic information is passed from generation to generation by DNA; DNA controls the traits of an organism. . (Game from Univ. Utah). Siguna. Mueller. PhD student in BMS, Univ. Wyoming. What is DNA?. Each cell needs instructions for its role in the body. What do these instructions look like?. The instructions come in the form of a molecule called DNA.. Karyotypes. To find what makes us uniquely human, we have to explore the human genome. . A . genome. is the full set of genetic information that an organism carries in its DNA.. A study of any genome starts with chromosomes, the bundles of DNA and protein found in the nuclei of eukaryotic cells. . Mendelian. Genetics, summarize the chromosome theory of inheritance and compare the consequences of mutations in body cells.
