When scientists clone a gene, they isolate and make exact copies of just one of an organism's genes. Cloning a gene usually involves copying the DNA sequence of that gene into a smaller, more easily manipulated piece of DNA, such as a plasmid. This process makes it easier to study the function of the individual gene in the laboratory.
To me a deep thinker is someone who is an innately curious, and deeply insightful. He/she has a profound understanding of the right questions to ask in the face of both reality and the unknown. He/she is not afraid to see reality and what is there before him/her.
Analytical Thinkers are reserved, quiet persons. They like to get to the bottom of things - curiosity is one of their strongest motives. They want to know what holds the world together deep down inside. They do not really need much more to be happy because they are modest persons. Many mathematicians, philosophers and scientists belong to this type.
