Researchers later isolate another residue that tends to be phosphorylated at position 259 of the aqp5 protein. if they desire to replicate the results described in the passage with a phosphomimetic mutant construct, this construct is most likely to be:

Mutagen

Explanation:

A mutagen is any substance capable of causing change in the base sequence of a gene.

It is usually SIMILAR in structure as the native protein or compound that binds to the receptor, and capable of Phosphorylation reactions as well

So, the construct is most likely a MUTAGEN.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
