Answer:
DNA is found in nearly all living cells. ... Although each organism's DNA is unique, all DNA is composed of the same nitrogen-based molecules. So how does DNA differ from organism to organism? It is simply the order in which these smaller molecules are arranged that differs among individuals.

Answer:
d) DNA that is patched together using DNA from multiple organisms.
Explanation:
GMOs are genetically modified organisms. The genome of these organisms has been altered using one or other techniques of genetic engineering. GMOs have recombinant DNA. A recombinant DNA refers to any DNA molecule that is made by combining genes from different organisms.
For instance, the human insulin gene is isolated from the human genome. The isolated gene is inserted into an <em>E. coli</em> plasmid vector molecule. The plasmid DNA molecule carrying the human insulin gene is an example of recombinant DNA. When this recombinant plasmid is introduced into the cells of the <em>E. coli</em>, they become GMOs.
Natural selection refers to the procedure where the species better amended to their surrounding appear to survive and generate more offspring. Natural selection refers to one of the mechanisms that make modifications in the frequencies of genes in populations and thus, it is the mechanism of evolutionary change.
However, the phenomenon of genetic drift and natural selection cannot take place unless and until there is a genetic variation, that is unless some individuals are genetically distinct from others.
