|
Who are Hershey and Chase?
They proved that DNA is the genetic material
|
What is an operon?
A cluster of genes with related functions, along with the control sequences
|
Who is Jean Baptiste Lamarck?
He proposed that species evolve by changing their traits through use or disuse of body parts, then passing the changes to offspring
|
What is adaptation?
The accumulation of diverse modifications
|
What is biogeography?
Geographic distribution of species
|
|
Who is Rosalind Franklin?
Scientist who made an X-ray crystallographic image of DNA
|
What is a repressor?
A protein that binds to the operator and blocks the attachment of RNA polymerase to the promoter
|
What is evolution?
The idea that earth's many species are descendants of ancestral species that were different than those living today
|
What is descent with modification?
The idea that present day species arose from a succession of ancestors
|
What are trace fossils?
Footprints and burrows
|
|
Who are Watson and Crick?
Scientists who discovered the base pairings of DNA
|
What are enhancers?
DNA control sequences in eukaryotes
|
Who is Charles Lyell?
He wrote the Principles of Geology
|
What is artificial selection?
The process of selecting and breeding individuals with desired traits over many generations
|
What is homology?
Similarity in characteristics that result from common ancestry
|
|
Who is Edwin Chargaff?
Scientist who discovered the amount of adenine in the DNA of one species is equal to the amount of thymine
|
What are microRNAs?
They bind to any mRNA molecule with the complementary base sequence
|
What is natural selection in the rock pocket mouse populations?
Natural selection observed in the New Mexico's Ring of Fire
|
Who is Thomas Malthus?
The economist who influenced Darwin's thinking about how limited resources affect populations
|
What is the Hardy-Weinberg equation?
The test for whether or not a population is in equilibrium
|
|
Who are Beadle and Tatum?
Scientists who proposed the one gene - one enzyme hypothesis.
|
What is alternate RNA splicing?
The process by which an organism can produce more than one polypeptide from a single gene
|
What is On the Origin of Species by Means of Natural Selection?
In 1859, Charles Darwin published the book titled
|
What are individuals do not evolve; populations do, natural selection amplify or diminish only heritable traits, evolution is not goal directed?
Three key points about evolution
|
What are: very large population, no gene flow between populations, no mutations, random mating, no natural selection?
The five conditions of Hardy-Weinberg equilibrium
