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.
Which of the following is NOT a method commonly used to insert genes into plant cells?
- Insert gene into Ti plasmid, then put them in contact with young plant cells
- Hybridization with close plant relatives that contain the wanted gene
-Fire a "gene gun" at a bunch of plant cells and hope they stick
-Insert gene into Ti plasmid, then inject plasmids into leaves
Genetic modification of plants:- Involves adding a specific stretch of DNA into the plant's genome, giving it new or different characteristics.
