What is the major difference between the eukaryotic genome and the prokaryotic genome?
The prokaryotic genomes are mostly single circular chromosomes. Eukaryotic genomes consist of one or two sets of linear chromosomes confined to the nucleus.
What are two key differences between bacterial and eukaryotic chromosomes?
In prokaryotes, the circular chromosome is contained in the cytoplasm in an area called the nucleoid. In contrast, in eukaryotes, all of the cell’s chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones.
How does the bacterial genome differ from human genome?
The human genome is comprised of 23 pairs of linear chromosomes, and approximately 3000 megabases (Mb) of DNA, while the genome of the bacterium Escherichia coli consists of a single 4.6 Mb circular chromosome. … Many of the well-studied bacterial model organisms, such as E. coli, have a single circular chromosome.
What are the similarities and differences between prokaryotic and eukaryotic genomes quizlet?
A prokaryotic genome is often a single DNA molecule whereas eukaryotic genomes usually consist of a number of DNA molecules. 2. Eukaryotic cells have membrane-bound organelles. Prokaryotic cells do not have membrane-bound organelles.
What are at least two major differences between eukaryotic and prokaryotic cells and one major similarity between the two?
Both prokaryotic and eukaryotic are similar in which they have a plasma membrane and cytoplasm; meaning all cells have plasma membrane surrounding them. A difference between Eukaryotic and Prokaryotic is that eukaryotic have organelles, for example, a nucleus. Prokaryotic cells do not have a nucleus.
What is one way that bacteria and archaeal cells differ from each other?
Bacteria and Archaea differ in the lipid composition of their cell membranes and the characteristics of the cell wall. … Bacterial cell walls contain peptidoglycan. Archaean cell walls do not have peptidoglycan, but they may have pseudopeptidoglycan, polysaccharides, glycoproteins, or protein-based cell walls.
What are 5 differences between prokaryotic and eukaryotic cells?
Prokaryotes don’t have membrane-bound organelles whereas eukaryotes have.
|Prokaryotic Cell||Eukaryotic cell|
|Lysosomes and Peroxisomes absent||Lysosomes and Peroxisomes present|
|Microtubules absent||Microtubules present|
|Endoplasmic reticulum absent||Endoplasmic reticulum present|
What is difference between eukaryotic and prokaryotic chromosomes?
The main difference between prokaryotic and eukaryotic chromosomes is that the prokaryotic chromosomes are short, circular DNA molecules whereas the eukaryotic chromosomes are long, linear molecules.
What are some differences in chromosome structures between prokaryotes and eukaryotes quizlet?
What are the key differences between prokaryotic and eukaryotic chromosomes? Prokaryotes have a single circular chromosome that is attached at one site to the cell membrane, whereas eukaryotic cells have free-floating linear chromosomes within a cell nucleus.
