The artificial manipulation, modification, and recombination of DNA or other nucleic acid molecules in order to modify an organism or population of organisms.
Genetic Engineering
organism first dominated the Earth
bacteria
the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
Evolution
involves cutting and pasting DNA segments from one organism into the genetic code of another. This process typically starts with isolating a gene of interest, using enzymes to snip it out of its original DNA strand.
Recombinant DNA Technology
the longest part of Earth’s history which covers 88% of the Earth’s history
Precambrian
Who proposed theory of acquired characteristics?
Lamarck
The practice of mating or breeding selected organisms with desirable traits
Classical Breeding
Age of reptiles
Mesozoic Era
this is a change in the DNA sequence of the gene.
mutation
These enzymes are called molecular scissors which is essential in making internal cuts in a DNA molecule or vector at specific sites.
Restriction Enzymes
Age of mammals
Cenozoic Era
The flow of alleles in and out of the population resulting from the migration of individuals or gametes.
Gene Flow
What do we call the new molecule after the process of ligation wherein the vector plasmid joined with the gene of interest?
Recombinant DNA
This era known as “Old Life”
Paleozoic Era
This mechanism of evolution was proposed two naturalists- Charles Darwin and Alfred Russell Wallace in the mid-nineteenth century.
Natural Selection
