Chapter 13 Test Flashcards
Give 2 reasons why a plasmid is used for DNA transfer
It has a DNA sequence that helps promote plasmid replication, ensuring that the foreign DNA will be replicant
It has a genetic marker- a gene that makes it possible to distinguish bacteria that carries the plasmid from those that don’t.
Describe what occurs in a successful transformation of cells
The recombinant DNA is integrated into one of the chromosomes of the cell.
How do scientist know that plants and animals share the same basic mechanisms of gene expression
A gene for luciferase, an animal enzyme works perfectly in a plant.
What is transgenic organisms
It is organisms that contains genes from other organisms
Genetic engineering has spurred the growth of biotechnology, a new industry that is changing the way we interact with the living world.

What is a clone
It isa member of a population of genetically identical cells produced from a single cell.
