Classification Flashcards
Who was the scientist that pioneered classification?
Carl Linnaeus.
What is the order of classification?
Kingdom
Phylum
Class
Order
Family
Genus
Species
What is the binomial system?
A name system consisting of two names: genus and species.
Which scientist developed the three domain system to classify all living organisms?
Carl Woese.
What are the three domains?
Archaea, bacteria and eukaryota.
What are the two characteristics of archaea?
Archaea can survive in extreme conditions and they have DNA plasmids in the cytoplasm.
What are the five animal kingdoms?
Animals
Plant
Fungi
Prokaryotes
Protists
Give three types of evidence that are used now to classify living things.
Classification system
Binomial system
Three domain system
Describe the first stages of genetic engineering including the use of:
a) restriction enzymes
c) sticky ends
Restriction enzymes are used to cut out DNA for insertion, the vector DNA is then cut open using the same enzyme.
The vector DNA and inserted DNA are left with sticky ends.
What happens during the stage of process of genetic engineering where ligase enzymes are used?
The vector DNA and inserted DNA are mixed together with ligase enzymes.
The ligase join the pieces of DNA together to make recombinant DNA.
What is the function of recombinant DNA and its impact on cells?
The recombinant DNA is inserted into other cells.
These cells will use the inserted gene to make proteins.
Many people are opposed to the growing of herbicide resistant crops produced by genetic engineering. Suggest one reason why:
The herbicide resistant gene may be picked up by weeds,
creating a herbicide resistant weed.
