After staying on the plant Earth reaching the human genetic technology, I have
come up with this report the four things I am going to talk about in this report
are: 1) What is the chemical basis of the plant Earth 2) What do human mean by
"genetic technology" and how is it possible 3) How have human used this
technology 4) Are humans concerned about this technology

1)The chemical basis of the plant earth is deoxyribonucleic acid (generally
shortened to DNA), it has the shape of a long twisted ladder each rung of this
ladder is made up of a pair of chemical bases, the information that human body
need to make proteins is coded and contained in the order of these bases along
the length of the DNA ladder. All DNA molecules consist of a linked series of
units called nucleotides. Each DNA nucleotide is composed of three subunits: a
special sugar called deoxyribose, a phosphate group that is joined to one end of
the sugar molecule, and one of several different nitrogenous bases linked to the
opposite end of the deoxyribose. DNA has two specific functions: to provide foe
protein synthesis, and hence the growth and development of the organism and to
furnish all descendants with protein-synthesis and hence the growth and
development of the organism. So all living things on plant Earth contains the
genetic material DNA and the structure of a DNA molecule or combination of DNA
molecules determines the shape, form, and function of the offspring.

2)The term "genetic technology"(or genetic engineering) is the modification of
the genetic properties of an organism by the use of recombinant DNA technology.
By using this technology it is possible to alert characteristics of living
organisms in specific ways. The chemical languages of DNA in all living thing
are the same so it is possible to take one gene from one living thing and
transfer into another living thing. To give an animal permanent genetic change
the new gene must be inserted into the single cell embryo from which all the
cell's will develop in the adult animal's body. It is much difficult to
introduce DNA into plant cells. So humans take one microbe that infects the
plant normally and puts it in a virus or bacterium and make the it carries the
DNA into the plant cell.

3)Humans has already used ‘genetic technology' and here are the three examples
of the living thing's human have used ‘genetic technology' on. First example is
the environmentally friendly cotton (cotton is any of various shrubby plants
grown for the soft, white, downy fibers surrounding oil-rich seeds' humans use
the fibers to make cloth). On the cotton there is a kind of pest called cotton
bollworm, it ate the fiber to live. Each year humans have to spend a lot of
money on pesticides to kill those worms. Now with ‘genetic technology' humans
