What else can I help you with?
The dust particles have exactly the same chemical composition as the gases of the interstellar medium?
Dust particles in the interstellar medium are made up of a variety of elements such as carbon, oxygen, silicon, and iron, similar to the composition of the gas. However, the dust particles can also contain complex molecules and compounds that are not present in the gas phase. Additionally, the physical and chemical properties of the dust particles can vary depending on their size, shape, and location within the interstellar medium.
Who discovered acid molecules which are now known as DNA in pus cells?
Emily dickerson
Who discovered DNA was a strand of molecules in a spiral form?
James Watson and Francis Crick.
What is interstellar matter made of?
The interstellar medium is an extremely sparse (tenuous) mix of gas and dust, some of the gas being ionized, some atomic, and some molecular. By composition the gas is largely hydrogen, with smaller amounts of helium and very small amounts of heavier elements. There are also cosmic rays which are protons and nuclei which have been accelerated to near-relativistic speeds. In cooler, high-density areas, the interstellar medium can become as dense as one ten-billionth that of air.
Which wavelength range in the electromagnetic spectrum has been the most fruitful in the search for organic molecules in space?
The radio wavelength range has been the most fruitful in the search for organic molecules in space. Radio telescopes have detected complex organic molecules in regions such as star-forming regions, comets, and interstellar clouds, providing valuable insights into the presence and chemistry of organic molecules in space.
Why can molecules survive in these clouds and not in other parts of interstellar space?
It isn't clear what you mean by "these clouds"; but in general, you would expect molecules to "survive" when the temperatures are not too hot.
Why atoms and molecules are invented?
The were not invented, they exist. Atoms and molecules were discovered.
What kinds of molecules have been found on extraterrestrial meteors?
Molecules like aliphatic carbon chains and minerals are found on meteorites but these are not unexpected. The truly interesting molecules that are found on meteorites include amino acids and nucleotide analogs, which are organic molecules that are essential to life as we know it.
When did they discover water molecules?
they discovered water molecules priestly in 1603 but they wanted to investigate water molecules so they knew if it was safe or not.
What is a interstellar cloud made of?
Since interstellar clouds are most often overdensities in the interstellar medium, they have overwhelmingly similar chemical compositions - most of them (about 90%) being hydrogen, although this may be molecular, or ionized (plasma), with most of the remainder being helium. Heavier elements and compounds have been discovered spectroscopically in interstellar clouds, including more recently some unexpected light organic molecules.
Recently scientists have discovered messenger molecules known as?
Peptides
The group of organic molecules that that were first discovered in the nucleus of the cell are called?
The group of organic molecules that were first discovered in the nucleus of the cell are nucleic acids. These molecules, such as DNA and RNA, carry genetic information and play vital roles in cell function and heredity.

What do scientist notice when they look at atoms and molecules using electron microscope?
By looking at atoms and molecules with this tool, scientists have discovered that often atoms a nd molecules are arranged in orderly patterns
