A researcher is studying the rl/ locus of phage T4. Three -- strains are obtained: A, B, and C. E. coli strain K(A) is coinfected with two rl strains simultaneously and the results are recorded. Infection with A and B phage lysis occurs Infection with A and C phage=lysis occurs Infection with B and C phage=no lysis occurs What can be inferred from this complementation test? Multiple Choice Strains A, B, and C have mutations in three different genes. Strains A and B have mutations in the same gene, and strain C has a mutation in a different gene. Strains A and C have mutations in the same gene, and strain B has a mutation in a different gene. Strains A, B, and C have mutations in the same gene. Strains B and Chave mutations in the same gene, and strain A has a mutation in a different gene.
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.
