3 is the answer.
Binary fission is a type of asexual reproduction and is the most common method of reproduction in prokaryotes. It may occur in some unicellular (single- celled) eukaryotes..
Eukaryotes use sexual recombination during reproduction to create or generate genetic variation and thus the resulting offspring will have a mixture of the parents' genetic characteristics.
Prokaryotes on the other hand will simply produce clones of themeslves through binary fisson. After the process of replicating its own genetic material, the prokaryote simply divides into two daughter cells that are almost identical in size and that concludes the process.

Answer: C) GMOs, genetically modified foods engineered in a lab to produce desirable traits.
Explanation:
The genetic engineering involves the insertion of genes from other organism to the host organism so as to make up genetically modified organism. Some unwanted and default genes are also removed from the organisms so that their body function properly.
The genetically modified foods are the examples of genetic engineering. This is done to produce desirable traits in the food crops. In plants both plants and animal genes are inserted to improve the yield of crops, and to improve their quality. In animals, the insertion of genes of other animals is likely to improve the milk and meat yield.
Answer:
Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. ... Nucleosomes fold up to form a 30-nanometer chromatin fiber, which forms loops averaging 300 nanometers in length.

Perhaps the answer your looking for is, a tumor suppressor gene.
