Answer: The correct answer would be amino acids. Translation is the process of formation of polypeptide chain in which nucleotide sequence of DNA is decoded to amino acid sequence via mRNA. It takes place at ribosomal site in a cell where mRNA is placed between small and large sub-units of the ribosome.

Polar molecules that include a hydrogen atom can form electrostatic bonds called hydrogen bonds. The hydrogen atom is unique in that it is made up of a single electron around a single proton. When the electron is attracted to the other atoms in the molecule, the positive charge of the exposed proton results in molecular polarization.
