Question

Eukaryotic chromosomes are composed of
(A)DNA + Protein
(B)DNA + RNA
(C)RNA + Protein
(D)Only DNA

Answer 1

Hint Without bundling, DNA particles would be too long to even consider fitting inside cells. For instance, if the entirety of the DNA particles in a solitary human cell were loosened up from their histones and set start to finish, they would extend 6 feet.

Complete answer:
Every chromosome in a eukaryotic cell is composed of DNA which is wound and dense around an octamer of essential proteins called histones.
To find a way into this compartment the DNA must be dense in some way. How much DNA is consolidated is communicated as its pressing proportion.

Additional information:
The histone proteins in these cells are H1, H2A, H2B, H3, H4 which are significant for the arrangement of chromosome structure or build-up of DNA. The length of DNA in the core is far more prominent than the size of the compartment in which it is contained.
The interesting structure of chromosomes keeps DNA firmly folded over spool-like proteins, called histones. For a life form to develop and work appropriately, cells should continually separate to deliver new cells to supplant old, destroyed cells. During cell division, it is fundamental that DNA stays unblemished and uniformly conveyed among cells.

So, the right answer is 'DNA + Protein'

Note: The term chromosome originates from the Greek words for shading (chroma) and body (soma). Researchers gave this name to chromosomes since they are cell structures, or bodies, that is emphatically recolored by some brilliant colors utilized in research. Chromosomes are a vital piece of the cycle that guarantees DNA is precisely duplicated and circulated in by far most cell divisions. In any case, botches do happen on uncommon events.
