A body of underground water, usually comprised of water saturated regolith, is permeable, and replenishes lakes and streams, is known as a aquifer.

Groundwater to be able to get into a rock with good porosity it must also have good permeability. For a rock to be permeable and for water to move through it, the pore spaces between the grains in the rock must be connected. Permeability is therefore a measure of the ability of water to move through a rock.

An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground. There are two general types of aquifers confined and unconfined.

The immune system not only fights pathogens; it also fights foreign cells, such as those introduced during tissue transplantation. This type of immune reaction is called Transplant or Graft rejection.

Rejection occurs when the recipient’s immune system recognizes the donor tissue as foreign or non-self, thereby, triggering an immune response. The major histocompatibility complex markers MHC I and MHC II which are more specifically known as Human Leukocyte Antigens (HLAs), play an important role in transplant rejection.

The immune response linked with a transplanted organ consists of both cellular (lymphocyte mediated) and humoral (antibody mediated) mechanisms. Although other cell types are also involved, the T cells are central in the rejection of grafts.

The unique chemical structure of the cell wall of mycobacterium spp. is associated with the presence of N-glycolyl muramic acid and an increase in lipid content.

Mycobacteria have strong, four-layered cell walls that are exceedingly thick. Peptidoglycan makes up the first layer, whereas lipids make up the subsequent layers. In order to maintain appropriate osmotic stability, peptidoglycan performs crucial activities like stiffness and rigidity. Bacteria are resistant to environments that are acidic and alkaline due to the presence of lipids.

All Mycobacterium species can be identified by their thicker cell walls, which are waxy, hydrophobic and abundant in mycolic acids. This is a characteristic that sets them apart from many other bacterial species. The mycolic acids make the mycobacterium less prone to antibiotics. Additionally, these molecules aid the bacteria in tricking the immune system and then hiding from it.

It is a chain termination method developed by Frederick Sanger and colleagues in 1977.

The process to determine the sequence of nucleotide bases in a part of a DNA molecule is called DNA sequencing. In the process of Sanger sequencing, the DNA molecule to be sequenced is copied multiple times by using polymerase chain reaction (PCR).

This creates DNA fragments of different lengths. Fluorescent labelled dideoxynucleotides are then used to terminate further chain formation.

This process marks the end of fragments and allows sequence determination. Therefore, a ddNTP is used in the Sanger Sequencing process. Compared to the normal DNA precursors, ddNTP lacks oxygen at the 3' carbon.
