Which came first in the evolution of life, DNA or RNA?
RNA likely came first in the evolution of life before DNA. RNA is thought to have been an early molecule that played a crucial role in the development of life on Earth.
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.
First molecule able to replicate itself?
The first molecule believed to be capable of self-replication is RNA, which is a type of nucleic acid. RNA can act as a template for copying and synthesizing new RNA molecules, a process that is essential for the propagation of genetic information and the early evolution of life. This self-replicating ability is thought to have played a key role in the origin of life on Earth.
Is an oxygen molecule an organic molecule?
No, an oxygen molecule (O2) is not considered an organic molecule. Organic molecules contain carbon atoms, while oxygen molecules do not contain carbon. Organic molecules are the building blocks of life and are typically associated with living organisms.
Which molecule did Carl Woese study to produce his tree of life?
Carl Woese studied the molecule ribosomal RNA (rRNA) to produce his tree of life, which led to the development of the three-domain system of classification - Bacteria, Archaea, and Eukarya.

What molecule do scientists believe came first in the evolution of life on Earth?
Scientists believe that the molecule that came first in the evolution of life on Earth is RNA (ribonucleic acid).
Is benzoic acid polar?
Benzoic acid is not a polar molecule because the overall molecule lacks a dipole resulting a slightly positive side and a slightly negative side. In a way you can think of the molecule as neutral and therfore has slightly greater non-polar characteristics. Experiments in which I have been a part in proves this to be true.

Why the discovery of sugar in space is a clue that life could exist around star?
The assumption is that life requires complex organic (i.e., carbon-based) molecules. Sugar, or other organic molecules, would be a first step. However, sugar is a fairly simple molecule; from sugar to life is still a huge step.
Do you think that men who like to dress in drag could have been females in a previous life?
I do not think that men who likes to dress in drag could have been females in a previous life.
What is the molecule that's responsible for unity and diversity of life?
DNA is the molecule that is responsible for unity and diversity of life .
If the first Queen Elizabeth had any men in her life how could she be a virgin queen?
Because she had never been a Queen before. The term has nothing to do with her Sexual experience.
How many people could have been carried on the first lifeboat on the titanic?
a good twenty people, but there were never enough life boats for all the passengers anyway

Where did first life develop?
The first life developed in the oceans. That was so long ago that it has not been possible to tell where or in which ocean.
Who discovered first life in Mars?
Life has never been proven to exist on Mars.
