Biodiversity
A measure of both species richness and species eveness
What is SIMPSON'S DIVERSITY INDEX?
The way in which an organism fits into an ecological community or ecosystem.
What is a NICHE?
The enzyme that 'unzips' the DNA molecule for replication.
What is DNA HELICASE?
Small scale changes in the allele frequencies within a population.
What is MICROEVOLUTION?
The technique that separates DNA fragments according to their sizes.
What is GEL ELECTOPHORESIS
The number of different types of species within an ecosystem.
What is SPECIES RICHNESS?
The maximum population size of a biological species that can be sustained in that specific environment, given the food, habitat, water, and other resources available.
What is CARRYING CAPACITY?
Insertion and deletion mutations can result in a non-functional protein due to...
What is a FRAMESHIFT?
A process in which the environment 'selects' which individuals will survive and reproduce.
What is NATURAL SELECTION?
The technique that amplifies large amounts of DNA from a small amount of template DNA
What is PCR (Plymerase Chain Reaction)?
An example of an interspecific hybrid that does not produce fertile offspring.
What is a MULE?
A species that is important for an entire ecosystem. Without it, the ecosystem would be dramatically different or cease to exist altogether.
What is a KEYSTONE SPECIES?
Proteins around which DNA is wrapped when not being replicated or transcribed.
What are HISTONES (accept NUCLEOSOMES)?
The transfer of genetic variation from one population to another.
What is GENE FLOW?
The enzyme that replicates DNA by extending a complementary strand.
What is DNA POLYMERASE?
A two part naming system for living creatures using the genus and species names combined.
What is BINOMIAL NOMENCLATURE?
A mathematical formula used to estimate population size by capturing, tagging and recapturing organisms.
What is the LINCOLN INDEX?
Chromosomes that carry the same genes, but each contains alleles from a different parent.
What is a HOMOLOGOUS CHROMOSOME?
Two subpopulations of a species evolve reproductive isolation from one another while occupying overlapping environments
What is PARAPATRIC SPECIATION?
The enzyme that joins fragments of DNA together.
What is DNA LIGASE?
A group of organisms that consists of a common ancestor and all its lineal descendants.
What is a CLADE?
The process relating to community growth or change that takes place when a habitat is disturbed or damaged.
What is SECONDARY SUCCESSION?
When a phenotypic trait is controlled by multiple genes.
What is POLYGENIC INHERITANCE?
An event that drastically reduces the size of a population.
What is a POPULATION BOTTLENECK?
Enzymes which cut DNA at specific sequences, used for making recombinant DNA.
What are RESTRICTION ENZYMES ?
