Researchers have identified a gene (FR) responsible for watermelon resistance to infection by Dacus curcurbitae (a close relative of Drosophila melanogaster). They isolate RNA from resistant (FR+) and sensitive (fr-) watermelons and use a probe that will recognize both FR+ and fr- transcripts. They also isolate protein from resistant and sensitive watermelons and perform a Western blot using an antibody that can recognize the fr- and FR+ protein. Describe the results illustrated below and give a plausible molecular explanation for these observations.
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.
