All living organisms utilize a complex machinery to duplicate their genomes and the central role in this machinery belongs to replicative DNA polymerases, enzymes that are specifically designed to copy DNA. “Hassle-free” DNA duplication exists only in an ideal world, while in real life, it is...

If all enzymes are proteins, are all proteins enzymes? About what percent of the buffering power of body fluids is found in the intracellular proteins? How many different types of enzymes are there in a typical human cell and how is their supply regulated?
Why are enzymes important to cells? What enzyme makes things fluorescent? How does pH affect enzymes? How are enzymes involved in regulating energy metabolism? What process typically regulates the enzymes involved in metabolic reactions? How do enzymes increase the rate of a chemical reaction?
On one hand, this allows enzymes and immune cells to reach the injury site; however, on the other hand, the distribution volume of hydrosoluble molecules significantly increases and consequently causes undesired effects (Liu et al., 2014). The release of various growth factors and cytokines ...
It contains proteolytic enzymes that help to destroy the outer layer of the egg cell, thereby allowing the sperm to enter into it easily. Nucleus Contains all the 23 chromosomes of the sperm cell, that is, half the genetic information of the future embrion. This is the only part of the ...
Bone marrow transplants are a common form of stem cell therapy used to treat diseases such as lymphoma, leukemia, multiple myeloma and neuroblastoma, while research is being conducted into the potential of TET2 enzymes found in hematopoietic stem cells to prime the body for leukemia. ...

If the EKG does not show a new heart attack and if the patient has stable symptoms, the next step depends upon the situation. Blood tests may be done to check cardiac enzymes. These are chemicals (troponin, CPK, myoglobin) contained in heart muscle cells that may leak into the bloodstream...
In vivo, the zona remains present until implantation (∼day 5/6 after retrieval) when it is believed to dissolve in response to the release of enzymes and cytokines secreted by the uterus. Thus, assisted hatching may lead to embryo division in two ways: first, a premature disruption in ...
