Complementary DNA, which is a strand of of DNA made using mRNA and reverse transcriptase.
A test strip of cDNA made from an mRNA sequence. A cDNA probe is used to determine exactly what gene codes for a particular amina acid.
A mutation the effects entire chromosomes (for example, when there are extra for a missing chromosomes or pieces of chromosomes).
the process of using a single cell or piece from an organism to grow a genetically identical organism.
A mutation in which one or more DNA bases are missing
A disorder characterized by the body's inability to produce or respond to insulin, resulting in high blood sugar levels
Frame shift mutation
An insertion or deletion of a base in a strand of DNA that causes the entire sequence of codons to change from there on out.
A laboratory technique used to separate biological molecules by size and charge. The technique is based on the movement of the molecules through an agarose gel in an electric field.
Sections of DNA that are unique to an individual.
Any of the cells in animals that can become gametes (sperm or egg).
A mutation in which one or more DNA bases are added.
A hormone that lowers blood sugar levels.
Pictures of chromosome pairs arranged by size and shape.
A point mutation that causes a codon to code for one amino acid rather than another.
An agent that causes a mutation in DNA. (Ex. Radiation).
A permanent change, corruption, or structural alteration in DNA or RNA. Mutations can be caused by radiation, mutagenic chemicals, or random chance events.
When homologous chromosomes or sister chromatids fail to separate properly in mitosis or meiosis.
A point mutation resulting in a protein that is too short by creating a premature stop codon.
A process in which the nucleus of one cell is transferred into another cell whose nucleus has been removed.
A gland behind the stomach that secretes insulin into the bloodstream and enzymes into the digestive system.
A mutation that changes a single base on a strand of DNA.
Polymerase Chain Reaction
A method for making a larger number of copies of a DNA fragment
Recombinant DNA technology
Combining segments of DNA from different organisms to manufacture a desired protein
An enzyme used in recombinantDNA technology to cut DNA at a specific site
An enzyme that uses RNA as a template for DNA synthesis rather than that other way around
A germ cell within a reproductive organ or tissue. A sex cell has the capabillity to produce sperm or egg cells through meiosis.
A mutation that has no effect on protein production.
Having to do with the body of a multi-cellular organism. A somatic cell is any cell besides a sperm or egg cell
An organism whose genome contains genes from more than one species.
The condition in which a cell has three copies of a chromosome rather than two.
