Homework Answers
Both eukaryotes and prokaryotes are composed of double stranded DNA.
Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
In Eukaryotes each chromosome contains a single double-stranded piece of DNA along with the packaging proteins. . Eukaryotes typically possess multiple pairs of linear chromosomes, all of which are contained in the cellular nucleus, and these chromosomes have characteristic and changeable forms.

Part A Which of the following statements accurately describes bacterial cell walls? In bacteria with acid-tast cell walls, the carboxylic acid in the walls forms a layer outside a thin layer of hydrophilic polypeptides. The cell walls of gram-negative bacteria contain many more layers of peptidoglycan than those of gram-positive bacteria. In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins Gram-negative bacterial cell walls contain teichoic acids, whereas the...
