Genetic Engineering
Recombinant DNA, or rDNA, is the term used to describe the combination of two DNA strands that are constructed artificially. Genetic scientists can do this to create unique DNAstrand for different purposes, using several types of techniques A plasmid is a small DNA molecule within a cell that is physically separated from a chromosomal DNA and can replicate independently. They are most commonly found in bacteria as small, circular, double-stranded DNA molecules; however, plasmids are sometimes present in archaea and eukaryotic organisms. A gene is a locus (or region) of DNA that encodes a functional RNA or protein product, and is the molecular unit of heredity. :Glossary. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. Genetic engineering (GE) is the modificationof an organism's genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. Transformation is a thorough or dramatic change in form or appearance

In standard 3.3.2 I learned that genetic engineering is the process of making changes in the DNA code of living organisms. I learned that some examples of genetic engineering are scientist making crops last longer and more nutrition. I also learned that insulin can be made from bacteria by the process of Bacterial Transformation. Some of the ways scientist does genetic engineering are to make medicine and vaccnes and to make crops resistant to weather and more nutritious.
This process is also known as “genetic engineering.” Genes of one species can be modified, or genes can be transplanted from one species to another. Genetic engineering is made possible by recombinant DNA technology. Organisms that have altered genomes are known as transgenic. Genetically modified organisms (GMOs) can be defined as organisms (i.e. plants, animals or microorganisms) in which the geneticmaterial (DNA) has been altered in a way that does not occur naturally by mating and/or natural recombination. A cell, group of cells, or organism that is produced asexually from and is genetically identical to a single ancestor. The cells of an individual plant or animal, except for gametes and some cells of the immune system, are clones because they all descend from a single fertilized cell and are genetically identical. |
Transforming Bacteria
Bacteria can be transformed using recombinant DNA
Plasmid- small circular DNA molecule
The plasmid has 2 essential features
Plasmid contains the foregin DNA must get into the bacteria cell
