Question

A cell has a circular chromosome and histone proteins associated with its dna, but lacks a nuclear membrane. Choose the domain of the cell with the best justification.

Answer 1

Answer;

-It belongs to Domain archaea

Explanation;

-Domain Archaea is any of a group of single-celled prokaryotic organisms (organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria as well as from eukaryotes.

-Eukaryote and archaea (ancient bacteria) both have DNA wrapped around histones to form chromatin.

-Eubacterium (true bacteria) do not contain histones.

-Eukaryotes have multiple linear chromosomes while archaea have a single circular chromosome.
