Term
Why are plasmids beneficial to prokaryotes.
Definition
They are resistant and can transfer that resistance to other species. Can form a capsule making it more resistant. These plasmids can eat hydrocarbons. They can change pigment. They can be used to produce antibiotics.
Term
Recombination happens between cells in the ____ ____.
Definition
Same generation
Term
DNA goes through transcription and translation to form what?
Definition
Protein
Term
Intervening regions of DNA are known as.
Definition
Introns
Term
An _____ is a nucleic acid sequence that is represented in the mature form of an RNA molecule
Definition
exon
Term
The regulatory gene is controlled by a ______ and an operator.
Definition
Promoter
Term
Promoters tasks?
Definition
RNA polymerase binding and start transcription
Term
What does the operator do?
Definition
Turns the promoter on or off.
Term
What does an active repressor protein do to an operator?
Definition
Stops it from turning of the promoter.
Term
Why would a cell use glucose before lactose?
Definition
The cell has to break down lactose into a usable glucose. Glucose is already a ready source of energy.
Term
Horizontal gene transfer is commonly known as?
Definition
Recombination
Term

Term
F- can only?
Definition
receive DNA
Term
when would a resistance plasmid be essential?
Definition
To protect itself from a vaccine.
Term
Why are plasmids beneficial metabolically?
Definition
They can transfer genetic material allowing other cells to use food sources they previously could not use.
