Which membrane give eukaryotes an advantage over prokaryotes in protecting their genetic material from damaging chemical changes?

Eukaryotes differ from prokaryotes mainly in that the organelles in a eukaryotic cell are bound by membranes. This protects them should harmful chemical reactions occur.

What is the evidence scientists have to support endosymbiosis and the evolution of prokaryotes to eukaryotes?
The difference between eukaryotes and prokaryotes is primarily that prokaryotes don't have membrane-wrapped organelles, including a cell nucleus containing its genetic material and mitochondria, the organelles that produce most of the eukaryote's supply of ATP, a source of chemical energy for cells. It is thought that organelles like the mitochondria evolved in eukaryotes as a result of endosymbiosis between prokaryotes. A similar origin has been proposed for chloroplasts in algae and plants. This is supported by the fact that these organelles contain their own DNA, and replicate independently from the host cell, as well as by their apparent genetic, morphological and behavioural relationship with various extant prokaryotes.
The disadvantage and advantage of chemistry to medicine?
chemical medicine is not good for health but even natural medicine is made up of chemical technics
Is mitochondria a power house?
Yes, mitochondria are cellular 'power plants' for eukaryotes. Mitochondria generate the cell's supply of ATP, a molecule which is used as a source for chemical energy.
How do eukaryotes obtain energy and nutrients?
they use the process hemolophotic which means they eat anything and take the nutrients out of what they need to survive. for example they may eat part of a leaf to get water.
What is purpose of rna editing?
RNA editing is when an RNA molecule is changed (edited) through a chemical change in the base make up. There are various types of RNA editing - namely insertions/deletions and switching bases like Cytidine to Uridine or Adenosine to Inosine (properly known as deamination). RNA editing has been observed in tRNA, rRNA and mRNA (interestingly enough all of them have to do with protein synthesis) of eukaryotes (in the cell nucleus, cytosol, mitochondrion, and chloroplast) but not in prokaryotes - which is interesting because both the mitochondrion and chloroplast are believed to be descended from prokaryotes.

What are two types of living things that biologists could study?
prokaryotes (which are bacteria and archaea) and eukaryotes (which are animals, plants, protists, and fungi). hope this helps
What do prokaryotes do in response to a chemical signal?
alter the level of production of various enzymes
How do the two members of the two domains of prokaryotes differ?
there are important differences in the structure and chemical makeup of their cells.Some prokaryotes are unicellular, and others are multicellular.Although bacteria and archaea are similar in some ways, there are important differences in the structure and chemical makeup of their cells.
What four characteristics are used primarily to identify prokaryotes?
list 4 factors that are used to identify prokaryotes What are four characteristics used to identify prokaryotes? Their shape The chemical nature of their cell walls The way they move The way they obtain energy A fifth is also gram stain
What is the chemical advantage of lever?
nothing
What are advantage of chemical change?
The biggest advantage of chemical change is life. All organisms are alive because of the sum total of all the chemical reactions occurring in their cells.
Archaea have a similar chemical makeup to bacteria?
like bacteria members of the domain archaea are unicellular prokaryotes
How are microorganisms classified?
Living creatures are divided into two key groups: the prokaryotes, where the DNA in their cells is not enclosed in a membrane-bound nucleus and the eukaryotes where the cells do have their DNA enclosed in a nucleus and often contain other membrane-bound organelles as well. The eukaryotes include fungi, protozoa, algae, plants and all multicellular animals. Prokaryotes include bacteria and the mysterious archaebacteria which are prokaryotic in general structure but also share some characteristics with eukaryotes. Viruses are akaryotic because they are non-cellular.
What are the advantage of biochemistry?
it tells us about chemical reactions in our body.
What is the history of mashed potatoes?
The nucleus of the eukaryotic cells contains the DNA of the cell and the associated proteins that form the chromosomes, and is separated from the cytoplasm by a double porous membrane. The outer nuclear membrane has a complex internal structure, part of which is covered with ribosomes, i.e., protein and RNA containing bodies which are the sites of protein synthesis. In aerobic eukaryotes, chemical energy is trapped in the microchondria, organelles bounded by a double membrane and containing an internal membrane structure in which are found both the electron transport system and the enzymes associated with respiratory metabolism. Mitochondria are absent in anaerobic eukaryotes. In photosynthetic eukaryotes, i.e., green algae, an organelle similar to the mitochondrion, the chloroplast, is found. Both mitochondria and chloroplasts contain small circular DNA molecules similar to those found in prokaryotes, ribosomes and other components of protein synthesis.
