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.
Explain the structure of basophils?
Basophils are a type of WBCs (white blood cells). They are the least common type of the granulocytes. They represents about 0.5 to 1% of the circulating WBCs. Basophils are the largest type of the granulocyte. They functions in inflammatory reactions during the immune response and also in the formation of allergic diseases such as asthma, anaphylaxis, hay fever, and atopic dermatitis. They produce some compounds that coordinate the immune responses. They produce heparin that prevents the clotting of blood, serotonin and histamine that induce inflammation,
Structure of basophils:
Basophil cells contain cytoplasmic granules that vague the nucleus under the microscope when it stained. When it is unstained, the nucleus is visible and has two or three lobes, but usually has two lobes. Their lobes are as well defined as of neutrophils. Their nucleus may appear as S-shaped. Basophils store histamine, which is a chemical compound secreted from the cells upon stimulation. When needed, these cells can be recruited out of the blood into tissue.
