Recombination dna technology is used to produce all of the following except,
a) human insulin.
b) cancer fighting drugs.
c) new genetic varieties of plants.
d) preferred genotypes for human offspring.

DNA recombinant technology does not help in the production of a new genetic variety of plants.

Further explanation:

Recombinant DNA is the process which is used to form different product after the fusion of DNA molecules which is extracted from the two different sources. It includes the isolation of genetic material. In this process, the required genetic material is isolated from the complete DNA strand. The second step is the restriction enzyme digestion. This enzyme acts like a scissor and helps in cutting the DNA at a particular location. The third step in amplification. It helps in creating multiple copies of a DNA sequence. DNA polymerase helps in amplification. The DNA molecules are joined by the DNA ligase (litigation) that results in the formation of recombinant DNA.

The insertion of a human gene into the bacterium becomes easier after the development of this technology. This bacterium helps in the formation of a protein encoded with the human gene.

Human insulin is the one and only protein formed by recombinant DNA technology. It helps in creating similar copies of natural human insulin (humulin). It is produced by using a yeast cell.

The recombinant DNA method helps in the production of interferon. Interferon is a glycoprotein secreted by the human cell in response to viral infection or cancer.

The formation of a new genetic variety of plants requires genetic variation. It is formed when a pollen grain of the one plant is fused with another plant. It helps in producing a hybrid that consists of the genes of both parents.

Keywords:

Recombinant, DNA, fusion, extracted, isolation, genetic, enzyme, polymerase, ligase, humulin, glycoprotein, pollen grain, hybrid.

the correct answer is option d.

an appositive is a noun, noun phrase or noun clause which follows another noun or noun phrase in order to describe it or name it another way. they are usually used between commas, brackets or dashes.

the example sentence with the correct use of commas is the following:

her uncle, the man over there in the red shirt, owns the hardware store in town.
