What else can I help you with?
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
Why have researchers rejected the idea that DNA was not found in the first life forms?
Researchers have rejected the idea that DNA was not found in the first life forms because the ability to store genetic information and replicate it is essential for life as we know it. DNA provides a stable blueprint for the organization and functioning of cells, making it highly unlikely that life could have originated without a molecule with similar properties. Additionally, evidence from the study of early Earth conditions and the emergence of life supports the idea that DNA-like molecules were likely present in the first life forms.
How long has DNA been around?
DNA has been around for billions of years, dating back to the earliest forms of life on Earth. It is the genetic material that carries instructions for the development, functioning, growth, and reproduction of all living organisms. The discovery of the structure of DNA was made in 1953 by James Watson and Francis Crick.
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.
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.
What varies in DNA to form different life forms?
The sequence of nucleotide bases in DNA, along with gene regulation mechanisms, determine the characteristics and functions of different life forms. Mutations in the DNA sequence can create variation, resulting in differences in traits such as appearance and behavior among different organisms. Additionally, the regulation of gene expression influences how genes are turned on or off, leading to diverse biological processes within organisms.
What would happen if you didn't have DNA?
We would't be alive without DNA,our body cannot produce new cells and then we all will die.In short,no life forms will ever exist
What are the forms of DNA?
If you mean forms as in shape, then spiral.
What forms part of the important life sustaining molecules such as DNA and RNA?
Nucleotides are the building blocks of important life-sustaining molecules such as DNA and RNA. These molecules consist of a sugar, a phosphate group, and a nitrogenous base, which combine to form the genetic information necessary for cell function and replication.
