Most appear to be some type of genetic flaw that manifests itself in the form of a knoblike outgrowth.
Although the tried-and-true method of hybridisation is just another type of genetic modification, the public seem to think that it is normal.
Meanwhile, Jillian Shapiro of Mount Sinai Medical School figured out away to get another new type of genetic material, called microRNA, into cells using viruses.
FORBES: 30 Under 30: The Rising Stars Transforming Science And Health
Friends of the Earth Europe, another anti-GMO group, says that the Sangamo technology may well turn out to be a type of genetic modification that it would oppose.
The power of this type of genetic analysis was demonstrated earlier this year when a study of 2, 000 breast cancers showed the cancer should be thought of as 10 completely separate diseases.
Dr. Zak wanted to see if he could find the genetic signature of this personality type.

Only last week scientists announced that they had linked several genetic mutations to an increased risk of developing type-2 diabetes.
Even if there was, there is thought to be only a one in 50 chance of the Whittakers having another child with the illness, so they would not be good candidates for this type of "pre-implantation genetic diagnosis".
Does this mean that we will soon see genetic tests that tell us whether we will get type 2 diabetes or whether we face heart problems later in life?
You may not have signs or symptoms if your pheochromocytoma is associated with a genetic condition, such as multiple endocrine neoplasia, type II (MEN II), because it's likely to be found on a scan before symptoms start.
Scientists say Type 1 diabetes is caused by a combination of genetic and environmental factors but they don't know what the trigger is.
Also in the cancer cluster were squamous cell carcinoma, a type of skin cancer, and throat cancer, but these had fewer genetic links between them.
Another type of test coming out of the genomic revolution involves looking at individual genetic mutations that are known to be associated with specific medical consequences.
They managed to extract the type of DNA found in the nuclei of cells (nuclear DNA) and genetic material from the cell's "powerhouses" - known as mitochondria.
The researchers cautioned that the study was done in only one type of cancer, and that more research is needed to see how much genetic variation there is in other types of tumors.
After several days, the ball of cells that results contains a blanket of embryonic stem cells endowed with the genetic material of the donor skin cell, which have the ability to generate every cell type from that donor.
