Every cell in a tissue sample has DNA
Centrifugation causes heavier substances to go to the bottom of a test tube
Gel electrophoresis uses an electric current to pull DNA across a gel
DNA is positively charged
Gel electrophoresis is used to shock the DNA so it "splits" open
Gel electrophoresis allows one to see the DNA and determine if extraction was successful
DNA can be used to determine the propensities of an organism to disease
DNA extraction allows scientists to determine mutations in a DNA sequence
PCR requires special enzymes to function at really high temperatures
PCR stands for Polymerase Chain Reaction
DNA can be amplified using PCR
It is easy to sequence small amounts of DNA
PCR is used to replicate a single or few copies of DNA
PCR is used to isolate only one gene within a genome
PCR is done to make DNA sequencing easier
PCR causes cells to replicate producing more DNA
To sequence DNA, dideoxynucleotides are used
DNA is made up of four different nucleotides
It is possible to sequence segments of DNA
DNA sequencing never works if the DNA contains mutations
DNA Sequencing defines the alphabetical order of the nucleotide bases
Knowing what the DNA sequence is for one gene determines the DNA sequence for the whole organism's genome.
The DNA sequence is essential for gene analysis
Today DNA sequencing takes too long to be useful
Computers are used to create the sequences of the DNA
Complimentary base pairing allows us to be able to create DNA sequences
Bioinformatics is using computer programs to analyze DNA
Bioinformatics is another name for a biological website
Bioinformatics is a technological application of biology
Bioinformatic is used to compare multiple DNA sequences
By knowing the DNA sequences we can know how the genes will be expressed
Bioinformatic Databases have allowed for easier comparison of genomes
Phylogenetic trees are also called cladograms
The same trait can never evolve in unrelated groups
Phylogenetics is the classification and naming of organisms
Phylogenetics shows how organisms relate evolutionarily
Phylogenetic mapping is made possible by molecular (DNA) sequencing
Phylogenetic trees are used to show evolutionary relationships
Phylogenetic trees help biologists understand how species are related
Phylogenetics helps classify species that aren't related to any other species
