DNA Basics
These are the 4 nucleotides found in DNA.
What are Adenine, Thymine, Cytosine, and Guanine?
This type of selection occurs when humans choose specific traits in organisms.
What is artificial selection or selective breeding?
This is the study of rocks.
What is geology?
This type of adaptation involves an organism's behavior.
What is a behavioral adaptation?
This is a type of scientist who studies ancient forms of life.
What is a paleontologist?
This is the number of pairs of chromosomes normally found in the human body.
Darwin developed these two theories during his studies.
What are natural selection and evolution?
This principle states that younger rock layers are deposited on top of older layers.
What is the principle of superposition?
This adaptation allows animals to blend in with their surroundings.
What is camouflage?
This scientist is known for developing the theory of evolution by natural selection.
Who is Charles Darwin?
This the whole process of making a copy of DNA.
What is replication?
A fossil that has characteristics of both ancestral organisms and organisms that evolved later (after it)
What is a transitional fossil?
This type of dating determines the exact age of a fossil or rock.
What is absolute dating?
This is the process by which organisms that are better adapted to their environment survive and produce more offspring.
What is natural selection?
This scientist used X-rays to study DNA and found the first indication that DNA has a helix shape.
Who is Rosalind Franklin?
This cell organelle is where proteins are built from the DNA copy.
What is the ribosome?
This process involves slight differences in inherited traits among individuals of a species.
What is variation?
This is a distinctive layer of rock that can be used to correlate rock units across wide areas.
What is a key bed?
This type of adaptation involves changes in an organism's body structure.
What is a structural adaptation?
This scientist proposed the theory of uniformitarianism in geology.
Who is James Hutton?
This type of mutation involves the replacement of a nucleotide in DNA.
What is a substitution mutation?
These islands fascinated Darwin on his expedition with the navy.
What are the Galápagos Islands?
This is a gap in the geological record where rock layers are missing.
What is an unconformity?
This adaptation involves one species imitating another for survival advantages.
What is mimicry?
These two scientists are credited with discovering the structure of DNA.
Who are James Watson and Francis Crick?
