comment Mass change in deamidation from Glutamine to Glutamate
@harpalss I'm currently reading papers/data from other sources and was trying to work out how they were doing it. The details seem to be glossed over rather a lot!

comment Why do you need you room dark for melatonin release?
Close your eyes and look at a bright light. Close your eyes in a dark room. See the difference?

comment Are there any methods to quantify H2O2 (hydrogen peroxide) which don't rely on horseradish peroxidase?
Titrate it with Potassium permanganate? phs.prs.k12.nj.us/rcorell/LabREDOXAnalH2O2.pdf

comment Mass change in deamidation from Glutamine to Glutamate
Ah, so the samples are put in acidic conditions to protonate the glutamate which can result in false positives, interesting.

Its more relevant to Biology as its to do with Proteins I think.

comment What is the viability of Intelligent Design as a supplement to chemical abiogenesis and Darwinian Evolution?
@AL You can always go the philosophical route and claim that an omniscient god would know that by creating a universe in a certain way how the randomness would produce human life through random processes. But there would be no testable predictions from this, since its indistinguishable from a situation without the omniscient god. That's a question for philosophy.stackexchange though!

comment What is the viability of Intelligent Design as a supplement to chemical abiogenesis and Darwinian Evolution?
If you look at any actual biological systems, its pretty clear they are too complicated to have been designed! Who would design a system with so much waste, multiple receptors and multiple ligands in each system, only a handful of which seem to actually do anything. The more you look at biology, the more absurd the idea it was designed!

comment Can methylation from DNA get copied to RNA during transcription?
ncbi.nlm.nih.gov/pmc/articles/PMC307917 This paper has the opposite view; that the rate of deamination is higher in the methyl version which accounts for its increased mutation rate.

comment How can pasteurized milk last 7 days?
In the UK pasteurized milk lasts around 7 days. I'd assume 7 days was pretty typical.

comment Are there examples of encryption in nature?
@JackAidley Well if you want to be pedantic they can be examples of Cryptography rather than Encryption, but its the closest example in Biology I can think of.

comment Are there examples of encryption in nature?
@JackAidley modern encryption is used for signing/verifying messages as much as encrypting/decrypting them. The RM system is a form of signing/verifying.

comment What is a Mitochondrial Eve and Y-chromosomal Adam
Just to note that you don't always get the mitochondria from the mother, sometimes you get some from the father too (but this is very rare.) This doesn't really change anything other than the "unbroken line of mothers" aspect.
