stuck in silence,
as time flies,
we close our eyes.
It’s hard to climb mountains,
or swim across the seven seas,
but at times like this,
we need some form of release.
Someone stand up and dance,
someone burst out a song,
someone sweep me off my feet,
yet I resorted to tweet.
Connections. Will write more…
If only everyone can be reasonable.
So there is a molecular biology test coming up in 2 days and I’m on the last part of revision learning about how there are glowing squids and how fireflies glow! Could not resist but to listen to the amazing song by Owl City 🙂
There are 2 lux operons. the first encodes luxR, a protein required to activate the second lux operon which is comprised of the genes lux I C D A B E G… the luxI gene encodes the enzyme VAI ( Vibrio fischeri autoinducer) sythase. VAI binds to the luxR protein. This complex then binds to the promoter of the second lux operon and assists RNA polymerase to bind.
The operon is then transcribed, producing more luxI, which in turn produces more VAI. This is a process called autoregulation. The operon is responsible fore producing a chemical that activates the operon. Complex yet clever! (Bearing in mind what I wrote in my last blog, I think that we can if we have not already taken this idea and incorporate it into some mechanical technology?!)
One of the proteins encoded by the second lux operon is luciferase. Luciferase then metabolises luciferin to produce a luminescent chemical- the came chemical that makes glow worms and fireflies glow :). –> The more VAI produced, the more luciferase produce.

I have always been awe struck at the physical world around us, which has been in my opinion one way or another extremely influenced by nature and biology… More so than our imagination. Nature of order and patterns have been explored by the incurably curious, therefore science has evolved to improve our everyday lives by exploring complexities in biology and biochemistry.
Perhaps as a biologist, I am biased on this topic of ‘creationism’ in saying that we are inspired more so by what is around us than what we can create. However, even if pure creations of the human mind can be extraordinary, nature has by the process of the astounding force of evolution, been perfecting its designs. Thinking about it, apart from living form on Earth, what other existences are able to self-improve in the same way? Do physical laws change or better themselves? Do rocks gradually become more beneficial in one way or another and are chemicals changing to benefit the rest of creation?
Here is an article from the BBC which encompasses difference bio-mimicry for us to ponder over:
Conclusion: Biology is awesome.
