DNA moves towards this end in gel electrophoresis.
What is the positive end?
100
How ddNTPs differ from dNTPs.
What is the lack of a 3'-OH?
100
The sum of all alleles at all loci in a population.
What is the gene pool?
100
The way a frequency vs. time graph would look like for a population experiencing balancing selection.
What is (shown on board)
100
Convergent Evolution produces these kinds of traits.
What are homplastic traits?
200
The polymorphism characterized by a heritable single base change.
What is a SNP?
200
The DNA barcode project uses this gene as a template for comparison.
What is cytochrome oxidase I?
200
GFP, normally present in fluorescent jellyfish, is an example of this kind of selectable marker.
What is a reporter gene?
200
The evolutionary force whose influence is greater with smaller populations.
What is genetic drift?
200
A phylogenetic group that does not include all descendants of a common ancestor is said to be this.
What is paraphyletic?
300
The 3 steps of PCR.
What is denature, anneal, and synthesis?
300
A collection of DNA copies from mRNA molecules from tissue that requires the use of reverse transcriptase.
What is a cDNA library?
300
The kind of selection that reduces variation in a population without changing the mean.
What is stabilizing selection?
300
Without changing the allele frequencies of the entire population, "selfing" changes the frequency of this genotype.
What is the heterozygote frequency?
400
Oligonucleotide probes are used in the direct screening of this polymorphism.
What is SNP?
400
An example of a vector for DNA present in bacteria that, unlike the chromosome, replicates autonomously and can be present in many copies in a single bacterium.
What is a plasmid?
400
The 3 propositions for Darwin's Theory of Evolution.
What is 1. Species change over time. 2. Divergent species share a common ancestor. 3. The mechanism that produces change is natural selection?
400
The evolutionary forces that act over very long periods of time.
What is mutation, genetic drift, and natural selection?
500
Discovery of this heat-resistant DNA polymerase enabled the development of the PCR.
What is taq polymerase?
500
How massively parallel sequencing was an improvement upon earlier methods of DNA sequencing.
What is the ability to sequence many different templates at once (parallel)?
500
The three kinds of selection and what each of them are.
What is
1. Stabilizing (purifying) Selection: average phenotype preserved.
2. Directional Selection: Favors individuals in one direction
3. Disruptive Selection: Favors individuals that vary in opposite directions from the mean.
500
The five conditions that must be met for Hardy-Weinberg to exist.
What is
1. Random Mating
2. Infinite Population
3. No Gene Flow
4. No Mutation
5. No Natural Selection?
