GEN BIO Flashcards
(66 cards)
Involves the use of molecular techniques to modify the traits of a target organism
Genetic Engineering
Is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells
Bacterial Conjugation
Specific process where exogenous genetic material is directly taken up and incorporated by a cell through its cell membrane
Transformation
Process by which a virus transfers genetic material from one bacterium to another
Transduction
Traditional way of genetic engineering which practices mating of organisms with desirable qualities and Recombinant DNA technology (rDNA)
Classical Breeding
_______ is the joining together of DNA molecules from two different species
Recombinant DNA technology
In this technique, a “gene gun” is used to fire DNA-coated pelletes used to transfer plasmid DNA into bacteria
Biolistics
The target cells are pre-treated to increase the plasma membrane’s pore size, making the cells “competent” for accepting the plasmid DNA
Heat Shock Treatment
This method is similar to Heat Shock Treatment, but the expansion of the membrane pores is done through an electric “shock”
Electroporation
______ is the introduction of genes into an individual for therapeutic purposes
Gene Therapy
Was the first genetically modified organism that was licensed for human consumption
Flavr-Savr (“Flavor Savor”)
Was developed to incorporate the production of a toxin from Bacillus thuringensis in corn plants
Bt-Corn
Was the first gets the power of the Sun and some prokaryotes or unicellular organisms are trying to eat and evolve to gather sunlight
The Cyanobacteria
The life has been started by the first and simple cell and they call it ________ which define as a microscopic
Prokaryotes
Some unicellular organisms evolve in multicellular organisms called ________ which defines as an organism consisting of a cell in which genetic material is DNA in the form of chromosomes
Eukaryotes
Means ‘ancient life’. The oldest animales on Earth appeared just before the start of this era in Ediacaran Period
Paleozoic (541-252 million years ago)
Marked by the evolution of hard body parts such as calcium carbonate shells
Cambrian Period
______ is a geologic period and system, the second of six periods of the Paleozoic Era
Ordovician (485.4-443.4 million years ago)
_______ system spanning 24.6 million years from the end of the Ordovician Period, at 443.8 million years ago, to the beginning of the Devonian Period
Silurian (443.4-419.2 million years ago)
______ system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, to the beginning of the Carboniferous
Devonian Period (419.2-358.9 million years ago)
Famous for its vast swamp forests, such as the one depicted here. Such swamps produced the coal from which the term _______, or “carbon-bearing”
Carboniferous Period (359.2-299 million years ago)
_______ stratigraphic system which spans 47 million years from the end of the Carboniferous, to the beginning of the Triassic Period
Permian Period (252.2 million years ago)
Nicknamed the _________, it is thought to have been triggered by catastrophic volcanic eruptions, resulting in dramatic environmental changes–including a runaway greenhouse effect and ocean acidification
The Great Dying
_______ was the “Age of Reptiles”
Mesozoic Era (251.9-66 million years ago)
