Agrobacterium tumefaciens Study guides, Study notes & Summaries

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 ...

What are some reasons to genetically engineer plants? increased yield and nutritional value Totipotent an entire plant can be generated from one cell Why is it important that plants are totipotent? If we can engineer one cell it will yield a fertile, transgenic plant 3 reasons for developing transgenic plants 1. improve agricultural, horticultural, or ornamental value of crop 2. develop plants that serve as bioreactors for the inexpensive productions of proteins/metabol...

frederick griffith - Answers studied streptococcus pneumoniae in mice - hypothesized that bacteria could "transfer" information to each other - S strain -> host death - R strain -> not fatal - pre-killing S strains prevents illness - killed S plus live R is fatal conjugation - Answers horizontal gene transfer requiring cell to cell contact - two cells brought together by pilus on the donor - relaxase assists in DNA transfer - requires presence of transferable plasmids -> co...
