for which of the following processes are enzymes not required? multiple choice replication self-assembly translation maturation
saveliy_v [14]

The process of assembling individual units of a material into highly arranged/ordered structures/patterns is known as self-assembly. Self-assembly processes are enzymes not required.

Self-assembly is the process by which a disordered system of pre-existing components forms an organized structure or pattern as a result of specific, local interactions among the components themselves, without the need for external direction. When the constituents are molecules, the process is known as molecular self-assembly.

What are the types of self-assembly?

Self-assembly is classified into two types: intramolecular self-assembly and intermolecular self-assembly. The term molecular self-assembly most commonly refers to intermolecular self-assembly, whereas folding refers to the intramolecular analog.
