What varies in DNA to form different life forms?
DNA contains the genes which determine what the life form will be.
What forms part of the important life sustaining molecules such as DNA and RNA?
Phosphorus is essential to living organisms because it forms a part of vital molecules such as DNA and RNA.
What do scientists think were the first characteristics of first life forms?
DNA I think
What forms part of the important life-sustaining molecules such as DNA and RNA?
Phosphorus
Do cells and bacteria have DNA?
Yes; all organic-based life-forms have DNA - it's how they know what to do when reproducing.
Why have researchers rejected the idea that DNA was not found in the first life forms?
It does not function as a catalyst.
Are organelles independent life forms in humans?
No, they are not. Except for mitochondria. These organelles actually have their own DNA
When do you get DNA?
assuming you mean the earliest developmental stages of life. Your dna is the result of the genetic material from your mother's egg and your father's sperm combining and copying itself as you gain more and more cells.
How could we possibly be aliens?
We can't. Our DNA matches up nicely with DNA from other Earth life forms, so we are native Earth beings.
What is DNA really?
DNA is a complex cell structure. It is the bases of all life in the world. It holds our genes and chromosomes. DNA was formed in the earliest period(pre Cambrian) made of a bunch of different elements. The first single cell life form was made. Then they got bigger and evolved. Then humans came to be . and DNA is a structure of many proteins and organism
Do plants have genes too?
Yes, all forms of life have DNA (genes) (some RNA, being bacteria).
Why do scientist believe that all life on earth evoloed from a sinlge-celled ancestor?
The coding of all DNA (and RNA) is the same for all life forms.
