Answer:
The correct answer will be option- C
Explanation:
The model organism is a non-human species organism used extensively in laboratories for genetic studies which acts as an ideal organism to another organism.
The concept of model organism began with the studies of the Gregor Mendel on pea plants and later several other organism like<em> D. melanogaster, C. elegans</em>, Yeast and others were used.
Since the<em> C. elegans</em> is a small roundworm and simple organism whose genome was sequenced in 1998 along with human genome in human genome project, therefore the C. elegans is used as a model which helps manipulation of genes of other genes.
Thus, option-C is the correct answer.

Answer:
Genetic engineering has its grass roots from the recombinant technology.
Explanation:
Genetic engineering is seen to have started from a scientists activity which involved restriction enzymes and DNA ligases that were used by Paul Berg in 1972 to create the first recombinant DNA molecules. A monkey virus which is SV40 was combined with a lambda one. Following that, the results of the experiment and attempts were further investigated by other scientists and later, the first plant that underwent genetic engineering was the plant tobacco.
