The production of new types of food crops will help raise the quantity of food grown by farmers. Research papers released by the National Academy of Sciences announced the development of two new superior varieties of rice--one produced by selective breeding and the other by biotechnology. One variety of rice, called Nerica (New Rice for Africa), is already helping farmers in Africa. Nerica combines the hardiness and weed resistance of rare African rice varieties with the productivity and faster maturity of common Asian varieties. Another variety, called Stress-Tolerant Rice, was produced by inserting a pair of bacterial genes into rice plants for the production of trehalose (a sugar). Trehalose helps plants maintain healthy cell membranes, proteins, and enzymes during environmental stress. The resulting plants survive drought, low temperatures, salty soils, and other stresses better than standard rice varieties. Which substance from bacteria was most likely inserted into rice plants in the development of the trehalose-producing rice? sugar

DNA also know as deoxyribonucleic acid, possess the genetic code of all organism and can be found in all plants and bacteria in which they are made up of molecules which is a sugar group.

DNA often tell cell what protein to produce in the organism and it contain all the genetic information of all living organisms or living things which are important to build and maintain the organism.

The molecule found in DNA contain two strands that work together in order to form a shape known as a double helix in which each strand always have a backbone which is been made of sugar and phosphate groups.

Almost every cell in a multicellular organism contains DNA which the organism needs, which is why Stress-Tolerant Rice, was produced by inserting a pair of bacterial genes which is DNA into the rice plants for the production of trehalose (a sugar).

Therefore substance from bacteria which was most likely inserted into rice plants in the development of the trehalose-producing rice is deoxyribonucleic acid commonly known as DNA.
