labeled mitotic cells (%) 100- 75- 50 25 0 bod 0 5 10 15 20 25 30 time (hours) a) Would cells at all phases of the cell cycle contain radioactive DNA immediately after the labeling procedure? Why? b) Why are there initially no mitotic cells that contain radioactive DNA? c) Explain the rise and fall and then rise again of the curve. d) Estimate the length of G2 for these cells e) Estimate the length of the total cell cycle forthese cells
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.
