comment Forum on synthetic biology and hypothetical biology?
Synthetic biology is currently at the level of constructing genetic circuits and modifying bacteria. We still don't fully understand all the details of how single-cell organisms work, so creating new types of animals is pretty far away.

comment Which turtle species was on board the Iranian Space Agency launch in 2010?
I apologize for the skepticism, but is there any indication this was a real turtle?

comment Are there special constants in biology that define organism's morphology?
Any scientific references on the appearance of the golden ratio in nature? From what I know this is highly debated.

comment Studying genetics
Actually, you might be surprised how relevant and applicable things such as statistical thermodynamics are to these processes... Try reading "Physical Biology of the Cell". OP see my answer at academia.SE.

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.
