Can Scientists Synthesize a Full Cell and Is an Empty Cell Considered Alive?

AI Thread Summary
Scientists have made significant advancements in synthesizing DNA, but the synthesis of a complete cell remains a complex challenge. Currently, a fully synthetic cell has not been achieved. An empty cell, devoid of genetic material, is not considered alive, as it cannot reproduce or pass on traits, which are essential characteristics of life. While an empty cell can initially perform some functions due to existing proteins in the cytoplasm, it will eventually die without the ability to synthesize new proteins. Thus, the notion of life in an empty cell is contingent on the presence of genetic material that enables ongoing cellular functions.

Dear all

Now -- as you all know -- scientists have reached the ability to synthesize a full DNA.

My question is:
Is it scientifically possible to synthesize a full cell? Can scientists do it?
And if yes, when scientists can possibly reach that stage?

Another question please:
When scientists placed the synthetic DNA into the empty cell, can we consider this empty cell (before placing the DNA) alive?
Was it alive when it was empty?


Thank you


Waiting for replies.


Best wishes

It's not alive until it has genetic matereal in it.
 
One of the characteristics of life is the ability to reproduce and pass on heritable traits to its offspring. Without any genetic material, an empty cell would not fulfill this criterion.
 
First of all, it is not possible to synthesize complete DNA.
Read Venter's & Co. article in the Nature journal.

to this:
"When scientists placed the synthetic DNA into the empty cell, can we consider this empty cell (before placing the DNA) alive?
Was it alive when it was empty?"

Well, it depends what you mean alive. YES, the first moments, the cell was able to perform it's functions due to the proteins remained in the cytoplasm. However, after a period of time the cell would die because no new proteins are synthesized. So you see, the cell wasn't empty, it just missed the blueprint for the protein production.
