At least 20 different types of tRNA molecules must exist in one cell to correspond to the 20 different amino acids used in protein synthesis. Each tRNA molecule carries a specific amino acid to the ribosome during translation.

Well, tRNA caries a single amino acid codon and no other amino acid codon, so about 64 types at least as that is the condon table.

How does isomer exist?

Isomers exist because of the different ways in which atoms can be arranged in a molecule while maintaining the same molecular formula. This results in different chemical properties and physical structures even though they have the same number and types of atoms. Isomers can be structural isomers, geometric isomers, or optical isomers depending on the type of arrangement difference.

Why does hydrogen molecule does not exist?

Hydrogen molecules do exist but they are less stable than hydrogen atoms. This is because hydrogen molecules require a large amount of energy to form since hydrogen atoms are highly reactive and tend to exist independently. Additionally, hydrogen molecules can easily dissociate into individual atoms at lower temperatures.


Why noble gases do not exist as molecules?

They have completely filled valence electrons, hence are stable, chemically inert. So they exist as mono atomic species and not as molecules


Why do molecules exist?

Molecules exist because atoms form chemical bonds with each other to achieve a stable electronic configuration. This bonding allows atoms to share or transfer electrons, leading to the formation of molecules with lower energy states. This stability allows molecules to exist in various forms and play essential roles in our world.
