Unsolved problems in biology

From Free net encyclopedia

Some unsolved problems in biology include:

Life. How did it start? Is life a cosmic phenomenon? Are the conditions necessary for the origin of life narrow or broad? Did life start on this planet or was there an extraterrestrial intervention (for example a meteor from another planet)? Is immortality possible?
DNA / Genome. What are all the functions of the DNA? Other than the structural genes, which is the simpler part of the system? What is the complete structure and function of the proteome proteins expressed by a cell or organ at a particular time and under specific conditions? What is the complete function of the regulator genes? The building block of life may be a precursor to a generation of electronic devices and computers, but what are the electronic properties of DNA? Does Junk DNA function as molecular garbage?
Consciousness / Self. What is it? Why is it necessary for many animals (especially mammals) to dream? What are the inheritable characteristics of intelligence?
Bioelectromagnetism: How do animals possess long-range navigation and migration abilities? How was the homing ability developed? How can some animals detect earthquake precursors? What are the effects of natural electric fields?
Viruses / Immune system. What are the signs of current or past infection to discover where Ebola hides between human outbreaks? What is the origin of antibody diversity? What is the relationship between the immune system and the brain?
Viking's methane. The Viking lander detected emissions of carbon-14-containing methane, which indicates the possible presence of life on Mars.
