comment How do we know that everybody's DNA fingerprint is unique?
Essentially, for the same reason we "know" that no one is going to be struck by lightning 100 times. It is possible but highly unlikely.

comment Length differences between physically interacting proteins
@Uri it seems like you mean to ask about 3D size rather than sequence length, is that correct? In other words, you are using sequence length as a proxy for some 3D size property.

comment How easy is it to carry out de novo sequence assembly?
@ThomasIngalls I mean assembling a complex genome de novo using high-throughput sequencing. Resequencing assembly is not de novo assembly.

comment Why isn't there a standard unit of promoter strength?
I think the quantity you suggest is suitable only if the relations between the different factors is linear. Is there any proof of that?

comment Why isn't a virus “alive”?
@nico actually you are mistaken. It is not true that the virus exists only when it is assembled into a capsid. The correct name is virus at all stages (you can check the definition). When it is in a capsid it is called a virion.

comment Why isn't a virus “alive”?
@nico a cell has a relatively clear definition and it must have its own membrane. A cell with double the DNA is not 2 cells, it is one cell with double the DNA. There is a point at which the cell divides and the membranes are separated - that is when it becomes a separate entity.

comment Why isn't a virus “alive”?
@nico that is why I wrote "the answer will be no for most people", i.e. under most definitions of life. I do not know of any robust definition of life that considers a piece of DNA to be alive. Also I completely agree with Jack - a cell is never a piece of DNA, under any possible definition.

comment Why isn't a virus “alive”?
@nico sorry I didn't understand - how is a cell a piece of DNA/RNA?

comment How do cells figure out the big-picture shape?
That is exactly what is studied in developmental biology, which is a huge field of research.

comment Has synthetic biology created new plants or animals as of 2013?
Can you define "new"? Is a genetically modified species "new"?

comment which exact mechanism triggers the first cell differentiation after n divisions?
There are two different questions here. One is how "identical" cells become different types of cells. The other is why do the cells start differentiating when they do.

comment What does “fit” mean in “survival of the fittest”?
Such definitions will always be lacking, in my opinion. For example, what if an organism has tons of grandchildren but they are all sterile?
