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...
