Unit 2: Clasification Flashcards
What is a species
Organisms which are similar to each other and capable of breeding to produce fertile offspring
What is classification?
The arrangement of organisms into groups
What is phylogeny?
The classification of organisms focusing on physical similarities
What is taxonomy?
Classification by using evolutionary relationships
What is DNA hybridisation
Went two organisms’ DNA is fused together by hydrogen bonds to see how similar they are
What is amino acid sequencing?
When scientists look at the sequencing of the amino acids to see how closely related organisms are
What are immunological comparisons?
When scientists look at the antibodies in different organisms to see how similar they are
What is courtship?
Selecting a mate before reproducing
How many groups are in the taxonomy hierarchy?
Seven
What is the first group in the taxonomy hierarchy
Kingdom
What is the second group in the taxonomy hierarchy
Phylum
What is the third group in the taxonomy hierarchy
Class
What is the fourth group in the taxonomy hierarchy
Order
What is the fifth group in the taxonomy hierarchy
Family
What is the sixth group in the taxonomy hierarchy
Genus
What is the last group in the taxonomy hierarchy
Species
During DNA hybridisation which bonds will form between the bases?
Hydrogen
During DNA hybridisation will it take more or less heat to break the bonds of DNA that are similar
More
What are proteins made of?
Amino acids
Related organisms have similar amino acids sequences. True or false?
True
What do immunological comparisons use to determine how similar to proteins are?
Antibodies
What do antibodies do to proteins
They bind them
Similar proteins from different organisms will bind the to the same antibodies. True or false
True
How is an organism names by the binomial system?
Genus species
