LacZ

The gene that encodes B-galactosidase in E.Coli

Population

A Group of interbreeding organisms of the same species which share a common set of genes

Allele Frequency

The proportion of a particular allele at a locus in a population

Continuous or Quantitative

A trait that displays a range of phenotypes due to many genes of small affect

Coactivator

In Eukaryotes, a large multiprotein complex that interacts with activators bound at enhancers and with RNA polymerase bound at the promote to stimulate transcription

Natural Selection

The differential reproduction of individuals in a population results from different in their genotypes. Also known, less correctly, as Survival of the Fittest

Trans-Dominant

Regarding partial diploid strains of E.Coli, the term for an allele that can rescue the effects of another allele somewhere else in the cell

Chromatin

The DNA-protein complex that constitutes eukaryotic chromosomes and can exist in various degrees of compaction

Balancing

selection which maintains polymorphism in populations

Heritability

the proportion of the total variance within a population caused by genetics. Also determined by the response to selection divided by the selection differential

Which of the these could cause a DECREASE in genetic variation BETWEEN populations? A.Migration B.Genetic Drift C.Inbreeding D.Directional Selection

Migration of individuals between populations and mating leads to mixing of alleles between populations so that the populations become more similar to each other.

Bioinformatics

Application of mathematics and computer science to store, retrieve, and analyze biological data, particularly nucleic acid and protein sequence data.

Monoploid

Condition in which a normally diploid cell or organism lacks one complete set of chromosomes

Spontaneous

Any mutation that occurs without the deliberate use of chemical or radiation

Transposase

An enzyme encoded by many types of mobile genetic elements that catalyzes the movement of these elements

Inversion

A chromosomal alteration that results in a segment of chromosome being excised then reintegrated at an orientation 180 degrees from the original orientation

Taq Polymerase

A heat-stable DNA polymerase used in PCR that was isolated from a bacterium found in a hot spring in Yellowstone National Park

Proofreading

In DNA synthesis, the process of recognizing a base-pair error during polymerization events and correction it

Transition

A type of base pair substitution that involves a change of one purine-pyrmidine base pair to othe other purine-pyrimidine base pair at a particular site in the DNA

Reverse Transcriptase

An enzyme that utilizes a RNA template to synthesize a complementary DNA strand

Genome

The total amount of genetic information in the chromosomes of an organism including its genes and DNA sequences
