Genome all the genetic material the organism contains Vertical transmission -from parent to offspring -same species (binary fission) Horizontal transmission -transfer of small pieces of DNA from one cell to another -different or same species 1) transformation 2) conjugation 3) transduction Transformation The process of importing free DNA into bacterial cells, cells need to be competent to do this (dead bacteria to live) Dr. Griffith -studied streptococcus ...

It is true that a eukaryotic cell: ○ Is smaller than a prokaryotic cell. ○ Contains structures called organelles. ○ Lacks a well-defined nucleus. ○ Does not contain histones. Eukaryotes are large, have membrane-bound intracellular compartments called organelles, has a well-defined nucleus, and have histones. The function of a histone found in a eukaryote cell focuses on cellular: ○ Division ○ Movement ○ Activities ○ Deoxyribonucleic acid (DNA) folding These proteins b...
