What types of biological structures and processes will the first proven extra-terrestrial (alien) organisms likely have?
Is it similar to life on Earth with DNA as the genetic material, RNA as an intermediate molecule, specific amino acids used to build proteins?
Silicon-based biochemistry instead of carbon-based chemistry?
Chirality and molecular asymmetry opposite to most Earth organisms (left-handed vs right-handed molecules)?
Cellular structures radically different from prokaryotic and eukaryotic cells?

3.00makes no sense to have amino acids + proteins (as we define them) without carbon-based biochemistry.
no, you can't just have silicon-based biomolecules by direct analogy to carbon-based life: https://manifold.markets/market/will-there-be-scientific-consensus-3a4a63bb4fac?tab=comments#pgajtj0m8he
@ArmandodiMatteo this market was made before the option for independent resolution existed. It will be resolved subjectively according to my judgement allocating some portion of 100% to every applicable answer.
