comment Does trypsin strip flask coating?
A small correction: PDL is not ε-amide, nonetheless the D-conformation would make it resistant to protease.

comment Does trypsin strip flask coating?
Generally the coating is of poly D-Lysine. Proteases act only on L-amino acids. Moreover the amide bond in PDL is between the ε-amino group & carboxyl instead of the α-amino group as in peptide bonds. So, I guess nothing should happen to the usual coated flasks. I have used the same flask for 2 rounds of trypsinization, and the cells seemed to be fine.

comment Is the attached digital camera on the top have the same magnification than visible in eyepiece?
This question appears to be off-topic because it is about technical specifications of microscope. Please go through the web pages of specific vendors for exact details.

comment What causes a polypeptide to fold into an Alpha helix over a Beta pleated sheet
I'll answer this question in a while. Meanwhile you can have a look at Ramachandran Plot

comment What causes a polypeptide to fold into an Alpha helix over a Beta pleated sheet
I don't think this is homework. This is about relative preference of structures (this is usually not explained in detail in textbooks)

comment Forum on synthetic biology and hypothetical biology?
what you ask for is not synthetic biology but science fiction. SF&F-SE would be a suitable forum for this kind of discussion.

comment Which organs in the body are responsible for measuring temperature?
As @inf3rno said there are thermoreceptors (TRPV ion channels) that are responsive to temperature. They are involved in temperature sensation of the environment as well as the body itself. I am not fully sure if they are the sole temperature sensors of the body. Have a look at these articles: [1], [2] and [3]

comment Dead skin cell decomposition
I don't think this is "Personal medication/health advice" question. But I suggest to the OP that they modify the question a little bit so that it sounds more general

comment Hill's function for translational regulation
It can be assumed that ribosomes are not limiting. If they were then protein synthesis would be globally affected which doesn't generally happen during the usual gene regulation (happens under drastic conditions such as UPR and stress). Regulator may not instantly find mRNA. We can adjust the rate constants accordingly. My doubt was mainly regarding normalizing regulator concentration with total mRNA for the hill's equation

comment Hill's function for translational regulation
See the edit. "Speed of translation" is not affected; just the rate of protein formation.
