Translation
The type of RNA that matches mRNA codons at the ribosome.
What is tRNA?
The most important protein in transcription?
What is RNA Polymerase?
A mutation with no effect on the resulting protein.
What is a silent mutation?
The ship Darwin collected his observations on.
What is the HMS Beagle?
True or False: Older fossils will be found in deeper layers of rock.
True
This site of the ribosome is where the tRNA carrying the next amino acid binds.
What is the A site?
The place where RNA polymerase binds to and starts building in eukaryotes.
What is the TATA box or promoter?
This mutation changes a base to code for a stop codon.
What is a nonsense mutation?
A process by which individuals with favorable inheritable traits are more likely to survive and reproduce
What is natural selection?
The contribution an individual makes to the gene pool of the next generation relative to the contributions of other individuals.
What is relative fitness?
A string of ribosomes that are translating mRNA at the same time.
What is a polyribosome or polysome?
A post-transcription modification.
What is a 5' cap, 3' poly-A tail, or splicing?
This mutation switches a base to a different one.
What is a substitution mutation?
What is descent with modification?
Structures with different appearances and functions that all derived from the same body part of a common ancestor
What are homologous structures?
The post-translational modification that is necessary to give proteins their function.
What is coiling and folding into a 3D shape?
RNA molecules that function as enzymes.
What is a ribozyme?
This mutation occurs when a single base is either inserted or deleted from the genetic code.
What is a frame shift mutation?
This is what actually evolves over time, not individuals
What are populations?
Structures with no apparent function but resemble features their ancestors possessed.
What are vestigial structures?
This enzyme forms the peptide bonds of the peptide chain.
What is peptidyl transferase?
The components of the transcription initiation complex.
What is the RNA Polymerase and the promoter?
This class of mutation alters a single base.
What is a point mutation?
The idea that geological changes resulted from gradual processes.
What is gradualism?
This examines patterns of species distributions.
What is biogeography?
