Is Non Carbon Based life Possible?

Could there be non carbon based life?

Answers

Well how far studied and the scientific facts shows that life without carbon is not likely to be possible.
Why life is possible due to carbon is here:
  1. Carbon is most abundant and perfect atom to be fitted in any biomolecule.
  2. Although there are lot of similar atoms which have same valencies like Silicon, lead, Germanium, and Tin but they have larger electron cloud size than carbon due to which they do not fit in aby biomolecule perfectly as carbon exist. Even many times in a same molecule.
  3. Carbon forms toxic as well as non-toxic components in a cellular system. Since they are all madeup of Carbon so they are easily transformed but when it comes for silicon, they form toxic elements.
There are some possibilities that life without carbon is possible:
  1. Perfect replacement of carbon which act like it and have same physio and chemical properties like carbon.
  2. If not then any atom have four valencies but an replacement of oxygen atom because the atoms known either degrade or form toxic components when comes in contact with oxygen, so an alternative atom must be present if you are expecting Silicon, Germanium, or Lead.
  3. Second most thing it should be abundant biologically and form approx 90% or more than of biomass.
How far I know or the current research is depicting :- that Carbon and its derivatives are found in other planets. Methane is also found on some places which is a good indicator of life.
If any of the molecule satisfies these points then yes It is possible
All I want to conclude is that the life evolved on earth 4.5 billion years ago (records says) and through this long time only capable and molecules have bioactivity are able to form a living system. Those who are not are still harmfull for us either in small amounts or in any other way..

Human Gene Editing Could be a key to immortality!

Human gene editing could be the key to advancing towards immortality. But even so, is this grounds for humans to do so? Should humans become immortal?

Question for you





Human Gene editing for becoming immortal or other experimentation is not ethical as per the human perspective and safety. This is because the technology was invented to cure and treat the genetic inborn diseases which increases the lofe expectancy, not to become immortal. Gene Therapy | Medical Evolution read this article for more information.

As Humans are most intelligent and can take their decisions own they can do this. But humanity doesn't allow this. Because wvery species posses wild genome aka its original genome content. If any change occurs the species become polluted however they are beneficial for us but they are unnatural. Second thing nature restricts these unnatural things for example mules and transgenders whjch have genetic alterations they naturally become infertile so they can nkt comtinue their generation, hence naturally eliminated from the nature.
The next question is Should Humans Become Immortal?
So, its upon the human population that what is wants. However nature has their own rules and regulations to run the ecosystem and limited resources. So doing yhis humanity will face a lot.
So, you should conclude here what you got! Please comment.
I concluded that gene wditing is a good technique to eradicate the genetic diseases and improve the life expectancy of patients. However if this technology may bring immortality than human beings grow tremendously and humanity will face a lot in terms of resources. Environmental Pollution caused by human over past decades.[1]
Think, At this population level we are harming our environment at alarming rate if we will become immortal than what else we can do?

Water | Nutrient or Not!

Nutrients are the biological molecules or chemical compounds which are required for the growth and development of an individual or cell.  The nutrients are classified in to two categories based on the carbon content,  Organic and Inorganic nutrients. 
The nutrients which have hydrocarbons as their backbone are Organic nutrients and those who doesn't lacks hydrocarbons as backbone are inorganic nutrients. 

Broadly, in terms of food nutrients are proteins, vitamins, minerals and  carbohydrates. These my be organic or inorganic. 

Any chemical compound is considered as nutrient when it is essential for the organism or cell or have significance in the bio-chemical pathway of the cell. 

A nutrient must have following properties: 

  • It should be bio-active and bio-available. 
  • It must contain hydrogen or carbon in its chemical structure.
  • It should be metabolized.
  • It should be required in adequate manner. 
  • Nutrients must be a source of energy or any molecule which is responsible for energy or biological factors. 
Water is required by any cell because it is universal solvent and have unique properties.  It is metabolized by body and have significance in various biological pathways.  Water does not contributes in the production of energy or any other molecules but helps in the formation and packaging of several bio-molecules.
