Given that the main reason for which an artist will retrace a drawing in pen is to <u>correct errors </u>and achieve a <u>final draft</u>, we can compare this to the biological process of DNA proofreading. 
DNA proofreading is a <u>biological process </u>that takes place during the biosynthesis of DNA. During this time, a chain of <u>DNA </u>is read and a complementary chain is creating, <u>effectively duplicating the genetic code</u>. 
During this process, DNA proofreading takes place. This is described as a process in which the DNA polymerase retraces the genetic code, detecting and fixing any errors in the synthesis before the strand is closed once again. 
The fact is that both processes, despite taking place in astronomically different situations, share a final goal which is to prepare the "product" for the "final draft". This allows us to draw <u>valid</u> <u>comparisons </u>between the retracing of a <u>cartoon </u>and the <u>proofreading </u>of <u>DNA </u>by the DNA polymerase enzyme.

The ability of a cell or a body to fight against the infection is called immunity. The T cell and B cell helps the body to fight against the infection.
<h3>
What are T cells?</h3>
T cell is also called as T lymphocyte, it is also a important part of immune system. T cell originate in the bone marrow and mature into the thymus.
There are three types of T cells:
- T helper cell
- T killer cells
- T cytotoxic cells.
Helper T cells secrete chemical messengers called cytokines. Regulatory T cells helps to control immune reactions. They are released into blood streams. 
Therefore, The ability of a cell or a body to fight against the infection is called immunity. The T cell and B cell helps the body to fight against the infection.

Answer:
Therefore, a global zoonotic disease surveillance system to reduce the emergence of zoonotic diseases in humans and to help detect other livestock diseases early could help to prevent the staggering economic losses associated with zoonotic disease outbreaks. So, yes I would say that they are very important to study.
