Answer:
The statements which are correct are:
-85% of the U.S. corn is GMO; modified to be resistant to herbicides.
-Technology now allows us to transfer genes between organisms of different species and even kingdoms.
- Extensive testing has been conducted on GMO-foods to ensure that there will be no adverse allergic reactions or health risks.
Explanation:
GM foods can be described as the food which is genetically modified. In simpler terms, food prepared by the introduction of a foreign gene is termed as genetically modified food.
About 92 percent of the corn produced in the U.S is genetically modified and out of it about 85 percent is genetically modified to be resistant against herbicides.
The use of GM foods was made legal after passing through various tests in the laboratory and being approved by the FDA. Up till now, any food prepared by this method is properly tested and approved By FDA before introducing it into the market.

Ans.
Chromatin molecules are made up of DNA and histone proteins. Modification of chromatin structure include covalent, post-translational changes in histone proteins, present in chromation. Acetylation and methylation are two important histone modifications that affect structure of chromatin molecules.
Acetylation involves addition of an acetyl group to histones that increases transcription of DNA by loosen the association between DNA and nucleosome.
Methylation involves addition of a methyl group to histones that results in condensation of chromatin molecule and thus, decreases transcription of DNA.
Both acetylation and methylation are reversible processes.
Many chromatin modifications are genetic, means they can pass from one generation to another generation, called epigenetic modifications.
Thus, options B), C), D), E), and F).
