Evolution
A change in gene variation over time.
What is evolution?
This type of sequence is used when transcribing DNA into RNA.
What is a complementary sequence?
This hypothesis states that viruses arose from free living cells and lost many functions during evolution.
What is the devolution hypothesis?
This type of regulation occurs from transcription beyond translation.
What is eukaryotic gene regulation?
These types of populations are more susceptible to genetic drift.
What are small populations?
In order for this to occur, genetic variation must be present in a population.
What is natural selection?
What is mitochondrial genomics?
This law states that the randomness of the universe is constantly increasing.
What is the Second Law of Thermodynamics?
This is a type of hydrophobic ligand used in cell signaling.
What are steroid hormones?
The sum of all the alleles in a population.
What is a gene pool?
This type of evolution causes populations to change over time.
What is microevolution?
The removal of introns from a product.
What is splicing?
This hypothesis states that the origin of viruses focuses on viral genetic material.
What is the escapist hypothesis?
This process converts a ligand bound to a receptor into a change in the cell.
What is signal transduction?
The less common types of alleles.
What are variants?
This form of isolation can be caused by any physical barrier in the environment.
What is geographical isolation?
DNA replication takes place in this direction.
What is 5'-3'?
This law addresses the conversion of energy to different forms.
What is the first law of thermodynamics?
Peptides are an example of these ligands used in cell signaling.
What are water soluble ligands?
These chromosomes contain fragments of DNA exchanged between homologues.
What are recombinant chromosomes?
Two structures that evolved for the same purpose, but are not ancestrally related, are said to be this.
What are analogous structures?
These must bind to the DNA to begin transcription in Eukaryotes.
What are transcription factors?
This law by Mendel tells us that every possibility of allele combination is equally likely and genes do not influence each other with sorting.
What is the law of independent assortment?
The key idea of this regulation is controlling accessibility to transcription factors through histone remodeling.
What is epigenetic regulation?
This type of organism received foreign DNA from a different species through genetic manipulation.
What is a transgenic organism?
