Transgenic (GMO) Tomatoes The use of pesticides to control insects costs billions of dollars every year. Genetically modified organisms (GMOS) are an attempt to reduce this cost. Tomato plants that are genetically modified can make proteins that are poisonous to the insects that feed on them. Using these GMO tomatoes would reduce the need for the chemical control of insects. 1. State one possible advantage of having tomato plants that make proteins that are poisonous to insects. 2. In biology, a trade-off exists when one trait cannot increase without a decrease in another. What trade-offs exist in the creation of transgenic tomatoes? 3. Question Answer _28. Some famers currently grow genetically engineered crops. An argument against the use of this technology is that 1) t increases crop production 2) it produces insect-resistant plants 3) its long-tem effocts on humans are still being investigated 4) it always results in crops that do not taste good
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
