Aprotein containing more than one polypeptide chain exhibits the level of protein structure. a)primary b)secondary c. tertiary d. quaternary e)infinite d 3.14 factual recall42

I think so the answer of this question is Quaternary.

Explanation:

Many proteins are made up of a single polypeptide chain and have only three levels of structure However, some proteins are made up of multiple polypeptide chains, also known as subunits. When these subunits come together, they give the protein its quaternary structure.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
