Digging deep: DNA molecules in ancient dirt offer a treasure trove of clues to our past

A dose that we typically get on a daily basis. then the researchers examine the cells using all the bio analytical methods out there disposal. the results are on him big us. smoke has a critical effect on human lung cells. the cells exhibit inflammation. a number of aggressive molecules form inside them triggering what the researchers call oxidative stress. the cellular metabolism undergoes an abrupt change as the cells attempt to defend themselves against the toxic substances. and theres also d...

Passed on from one. generation to the next are not identical during the inheritance process eris and changes take place in the molecular structure these so-called mutations. these small scale changes have made possible the great diversity of life as we know it today which makes at least more recently covered. the mechanisms of d.n.a. replication are not perfect and often lead to errors that i mean its just enough intersex there are also external factors that can modify the d.n.a. molecules. thes...

Contains d.n.a. molecule its. all the genetic information thats required for the formation of an organism not any more. and its because here they used to produce a plant known as months there are also if you want but if youre. not the copies that are passed on from one generation to the next are not identical during the inheritance process eris and changes take place in the molecular structure these are called mutations. these small scale changes have made possible the great diversity of life as...

A plant known as monster. if you want but if youre sick. but the copies that are passed on from one generation to the next are not identical during the inheritance process eris and changes take place in the molecular structure these so-called mutations. these small scale changes have made possible the great diversity of life as we know it today which mechanism or has been implicated in. the mechanisms of d.n.a. replication are not perfect and often lead to errors but the communities thing after ...

Grigori if later discovered that the carcass was over twenty eight thousand years old he had often heard stories of how locals fed mammoth meat to their dogs but this was the first time he had actually come face to face with beautifully preserved mammoth flesh. in this tissue which is tens of thousands of years old we are hoping to find living cells thats not easy of course almost impossible in fact . by studio with the war. the cell nucleus could be implanted into the egg of a female asian elep...

According to the american cancer society, cancer is the second most common cause of death in the united states, exceeded only by heart disease. and it accounts for nearly one of every four deaths. here to talk about this new research dr. bob laheda, chairman of inned sick -- medicine and professor of medicine at rutgers medical school. the majority of cancers could be just random? >> actually, john, i dont agree with this at all. theyre saying two-thirds of the cancers that we getting out of luc...

That can have serious effects on the human body. >> were going to take a look now at how radiation can affect the body. weve prepared this chart here. were going to start in the thyroid. you may have heard those iodine pills you can try to take to try to protect the thyroid. radioactive iodine exposure raises long-term risk of thyroid cancer. moderate to heavy radiation can cause nausea, vomiting, and diarrhea. it can affect your bone marrow cells. none of these alone is fatal. were going to tal...
