An average Human cell (diploid) contains about 6.4 billion base pairs of DNA divided among 46 chromosomes. The length of each base pair is about 0.34 nm. Therefore, if the DNA molecule in a diploid cell were laid out end to end, the total length of DNA would be approximately 2 meters. Continue reading How a 2 meters long DNA is fitted into a 2 micrometers Nucleus?
Several strategies can be used to prevent the emergence of Antibiotic Resistance.
- We can use antibiotics in reasonably high concentrations to destroy susceptible bacteria and most spontaneous mutants, which may arise during the treatment period. Continue reading How can we fight against Antibiotic Resistance?
Bacteria often become resistant through different kinds of mechanisms. One kind of mechanism is never confined to any specific class of antibiotics. Different resistance mechanisms are used in different bacteria to confront the same antibiotics.

Fifty years ago people believed that the war of humankind against the infectious diseases was virtually over and science had won over infectious diseases such as pneumonia, whooping cough, polio and small pox with the help of antibiotics, vaccines, and some aggressive public health campaigns.
It is a well-known fact that DNA acts as a genetic material in most of the organisms on this planet earth. However, it is also clear that RNA also acts a genetic material, but only in some viruses (for example, Tobacco Mosaic Viruses, QB Bacteriophage, etc.).

Organ Transplant is a process of picking an organ from one individual and placing it in a different individual, such as a kidney transplant. It is generally carried out to replace a diseased organ by a healthy one. The organ transplant may sometimes lead to various complications in the individual receiving that organ. These complications are mediated through host body immune responses against antigens of the transplanted organ. Continue reading All You Need To Know About Organ Transplant.
The discovery that genetic information is coded along the length of DNA was one of the major achievements of science in the 20th century. This polymeric molecule, DNA, is the chemical basis of heredity and is the fundamental units of genetic information.

Biosphere Reserves (BRs) are specified areas of natural and cultural landscapes that include minimally disturbed, man-modified and degraded ecosystems. These are meant for preserving genetic diversity in various natural biomes.
