This process involves taking dna and placing in into a different cell

Transformation

Explanation: The DNA of interest is taken and first inserted into an organismal genome, like bacterial plasmid or some vector etc. This leads to the formation of Recombinant DNA which is then placed into the host cell which can be a bacteria cell. Hence Transformation or genetic alteration occurs by the insertion, uptake, incorporation of the Recombinant DNA into the new host cell.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
