It might be proteins, proteins make up the enzymes and material that you use to see, and process info.Enzymes break down material etc. DNA, RNA, and ribosomes are all confined to cells, proteins are exported.

i do no longer probably get your question with the excellent serves to have interplay with the international element. yet, each and every cellular desires proteins to stay. So, i might wager proteins. DNA holds the genes to make the proteins. for the reason that DNA might desire to stay interior the nucleus, RNA is mandatory. RNA is transcribed and then heads out of the nucleus into the cellular. The nucleus would not enable something with thymine get out, because of the fact of this RNA replaces it truly is thymine with uracil. So, then the RNA is translated to make a protein. Ribosomes are organelles that make proteins.

DNA is indirectly affected and directly affected. For example, radiation can mutate DNA (direct). Or, the environment can act on the phenotype (the expression of DNA in traits, such as long legs or blue eyes) via natural selection, which indirectly acts on DNA.
RNA can similarly be destroyed by outside influences (radiation, high concentrations of molecules, like salt). However, it is more often affected by intracellular conditions.
Proteins do interact with the world. Your eyes are made of proteins, for example, as are nails. Also, however, proteins are synthesized as a response to the environment. For example, if you suddenly ingest metal, accidentally or through inhalation, then certain proteins are synthesized that react to these metals. They encapsulate the metals and prevent immediate damage to the cell.
Ribosomes react about the same to the environment as does RNA. Random (stochastic) events may destroy them. Oh - RNA is the intermediate in protein synthesis, so what I said above about proteins goes for RNA, too. And, since ribosomes facilitate the translation fo mRNA to proteins, they're also involved in environmental response.

Yes! They all do. But, if this is a poorly conceived homework question, the answer is probably DNA. DNA is your primary mechanism for adapting to the 'world' in which you live.
