What level of protein structure is created during protein syntheisis?
Zolol [24]

Answer:

The correct answer will be - Primary structure

Explanation:

Proteins are one of the biomolecules formed by the process of translation.

Depending on the function they attain many structures like primary, secondary, tertiary and Quaternary structure.

The primary structure is the simplest structure formed by binding the amino acids via peptide bonds in linear order. This simplest structure is formed by the process of translation in which tRNA brings specific amino acids to the nascent peptide.

Thus, Primary structure is the correct answer.
