What forms the bond between neiboring amino acids

Proteins are formed by linking amino acids with peptide bonds, and the amino acid bond is also formed through a condensation reaction, where the carbonyl and the amine group link together with the release of water.

Rna polymeras should attache to the promoter.

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
