lecture note 4



DNA: Deoxyribo nucleic acid. is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. The main role of DNA molecules is the long-term storage of informations.make up human's genome

ARTIFICIAL LIFE: scienctists try to create lifelike human and tinker the human's genome.

INORGANIC LIFE: life can be formed out of any material capable of maintaining an order.
golem=robot

Artificial intelligence: per-set algorithms, designed to learn, uncanny capabiities

Molecular structure=chromosomes. DNA is the code of life. Chromosomes are the organized form of DNA found in cells. Chromosomes contain a single continuous piece of DNA, which contains many genes, regulatory elements and other intervening nucleotide sequences. A broader definition of "chromosome" also includes the DNA-bound proteins which serve to package and manage the DNA.(wiki) (A scheme of a condensed (metaphase) chromosome. (1) Chromatid - one of the two identical parts of the chromosome after S phase. (2) Centromere - the point where the two chromatids touch, and where the microtubules attach. (3) Short arm. (4) Long arm.) wiki

The organic life encoded messages togenome: 1 implemented genome
2 molecular biology

Change human's own genetic code is a social disputed problem.

Transplants: human's body can replaceable but limited.

ENOTRANSPLANTS: site somebody's body to other body.





DNA is made by many molecules which make the body and entail to their children. Scientists try to change the DNA and use the artificial DNA to create the new life. Dolly is an artificial sheep which born in 22-2-1997, Dolly is a clone sheep and she was just live for a short period. artificial can clone some anamals and plants. the clone also bring the distanage to human, some people ask whether human can be clong, it is a serious thing to human, people have to face the sexual reproduction to asexual reproduction , it is a degenaracy, the clone people have no parents, they will become apartness, when the clone people grow up they may use the sexual reproduction, it will cause the intermarriage. marriage, reproduction is the society responsibility for each people, each people have to have the obligation to responsibility, bring-up and support their parents. it suitable for the social develop.
