15-1 sub-Cellrar Genetic Elents as Gene Greatures

Livig cells can be viewed as providing habitats for viriuses and
other genetic elements

▪ sub-Cellrar: They rely on a host cell to provide energy and raw materials → Parasitic ▪ Gene Greatures: They lack their own cells but carry genetic information. → The cell it inhabits is simply its enviroment. ▪ transposon or transable elements: - Some of these genetic elements do not even exist as independent genomes. - Be found as lengths of DNA integrated into other DNA molecules. - Be able to move around from site to site within host DNA.

15-2 Most Mobile DNA Consists of Transposable Elents

▪ Mobile DNA: - Refers to segments of double-stranded DNA that move as discrete units from place to place within other DNA molecules. - Segments move from one site to another on the same larger DNA molecule. - May hop around from place to place among the chromosomes  → called “jumping genes”
