Cancer is a very complex disease having many causes.
What are some causes of cancer?
Cancer can arise spontaneously, but can also be induced as a result of
environmental factors such as sun exposure and smoking. If you were in charge
of allocating resourc
In human blood cells, the length of telomeres steadily declines over time from 8,000
base pairs at birth to 3,000 base pairs as people age, and as low as 1,500 in the elderly
(an entire chromosome has about 150 million base pairs). Each time a cell divide

One of the best ways to learn about a process is to study what happens when problems
arise in that process. Crossing over is a key process occurring in meiosis that leads to
