slavikrds [6]
The language of DNA in form of nitrogen bases read in a set of three termed as codons and it is being translated as language of proteins.

First mRNA is read according to the genetic code which can relate the amino acid sequence to proteins. mRNA can be use as the template to assemble in order the chain of amino acid. Translation starts when the mRNA is decoded and the sequence is elongated  until creating an amino acid sequence.

belka [17]

Answer;

-They all provide water

Explanation;

Therefore, the similarity of all the reactions is that they are all condensation reactions, with water as a common product.
