What are the tissue changes with age?Aging:When the cells become older this results in aging. All cells in the body experience aging. These cells become large, their ability to divide reduces. The pigments and fatty materials get incorporated into the cells of the body. These cells also ...

A glance at some numbers may support the notion that viruses are much more than just pathogens. There are 1033viruses on our planet, about 10 times more than bacteria. There are only about 109human beings – a small minority, which makes us the invaders in the viral world, not vice versa...

What are stem cells and how are they being used to change the future of medicine? Explain how telomeres are constructed using telomerase in embryonic stem cells. What is GMO? What is adulteration? What is the difference between bioengineering and biotechnology? What is the process of non-disjunc...
What role do telomeres and telomerase play in cancer progression? How many different forms of cancer have already been discovered? What are the functions of proto-oncogenes, oncogenes, and tumor suppressor genes? How does malignancy relate to cancer? What is metastasis and why is it incurable?
DNA could undergo transcription to provide RNA then translation will occur to provide the proteins needed by the body. Replication of the DNA requires energy, enzymes and substrate for the reaction to occur. Main enzymes for the reaction are helicase, DNA gyrase, DNA ligase and DNA polymerase....
