DNA was extracted from met leu his pro bacteria and used to transform met leu" his pro bacteria, which were then assayed for their nutritional requirements and the respective numbers of the following colonies were found: met leu met pro met+his+ + pro leu + pro his leu+ his 0 1 met 0 4 0 2 Which of the following maps is correct? And, which two genes are likely to be closest to each other? leu -- met -- his -- pro; met & leu and met & his and pro & his are equally close to each other ----------- pro ---- leu --------- his; pro & leu are closet to each other pro ----- leu -- his -- met ; his & leu and his & met are equally close to each other his promet -- his --------- leu ----- pro; pro & his and met & his are equally close to each other
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.
