Name one major difference between a prokaryote cell and a eukaryote cell

Biology

MAXImum [283]3 years ago

The prokaryote cell is simpler, and therefore smaller, than a eukaryote cell, lacking a nucleus and most of the other organelles of eukaryotes. There are two kinds of prokaryotes: bacteria and archaea; these share a similar structure. 

<span>Nuclear material of prokaryotic cell consist of a single chromosome that is in direct contact with cytoplasm. Here, the undefined nuclear region in the cytoplasm is called nucleoid. </span>

<span>A prokaryotic cell has three architectural regions: </span>

<span>On the outside, flagella and pili project from the cell's surface. These are structures (not present in all prokaryotes) made of proteins that facilitate movement and communication between cells; </span>
<span>Enclosing the cell is the cell envelope – generally consisting of a cell wall covering a plasma membrane though some bacteria also have a further covering layer called a capsule. The envelope gives rigidity to the cell and separates the interior of the cell from its environment, serving as a protective filter. Though most prokaryotes have a cell wall, there are exceptions such as Mycoplasma (bacteria) and Thermoplasma (archaea). The cell wall consists of peptidoglycan in bacteria, and acts as an additional barrier against exterior forces. It also prevents the cell from expanding and finally bursting (cytolysis) from osmotic pressure against a hypotonic environment. Some eukaryote cells (plant cells and fungi cells) also have a cell wall; </span>
<span>Inside the cell is the cytoplasmic region that contains the cell genome (DNA) and ribosomes and various sorts of inclusions. A prokaryotic chromosome is usually a circular molecule (an exception is that of the bacterium Borrelia burgdorferi, which causes Lyme disease). Though not forming a nucleus, the DNA is condensed in a nucleoid. Prokaryotes can carry extrachromosomal DNA elements called plasmids, which are usually circular. Plasmids enable additional functions, such as antibiotic resistance. </span>
<span>--------------------------------------... </span>
<span>Eukaryotic cells </span>

<span>Plants, animals, fungi, slime moulds, protozoa, & algae are all Eukaryotic. These cells are about 15 times wider than a typical prokaryote and can be as much as 1000 times greater in volume. The major difference between prokaryotes and eukaryotes is that eukaryotic cells contain membrane-bound compartments in which specific metabolic activities take place. Most important among these is a cell nucleus, a membrane-delineated compartment that houses the eukaryotic cell's DNA. This nucleus gives the eukaryote its name, which means "true nucleus." Other differences include: </span>

<span>The plasma membrane resembles that of prokaryotes in function, with minor differences in the setup. Cell walls may or may not be present. </span>
<span>The eukaryotic DNA is organized in one or more linear molecules, called chromosomes, which are associated with histone proteins. All chromosomal DNA is stored in the cell nucleus, separated from the cytoplasm by a membrane. Some eukaryotic organelles such as mitochondria also contain some DNA. </span>
<span>Many eukaryotic cells are ciliated with primary cilia. Primary cilia play important roles in chemosensation, mechanosensation, and thermosensation. Cilia may thus be "viewed as sensory cellular antennae that coordinate a large number of cellular signaling pathways, sometimes coupling the signaling to ciliary motility or alternatively to cell division and differentiation." </span>
<span>Eukaryotes can move using motile cilia or flagella. The flagella are more complex than those of prokaryotes.

Hope this helps!! (If not I'm sorry!)</span>

Why did scientists many years ago believe that protein was the storage molecule for genetic information, instead of DNA?
Neporo4naja [7]

Answer:

Many years ago scientists believed that protein, DNA is not the genetic material because of many reasons like DNA is made up of only four type of nucleotides while proteins are made up of 20 different types of amino acids. So the building blocks of protein are way high than DNA.

Most of the cellular function is performed by proteins, not DNA. The three-dimensional shape of protein is much higher than nucleic acid. So as protein heterogeneity was high therefore it was considered as a molecule of genetic information instead of DNA.

Which immunization is available to prevent communicable disease and illness? Question 11 options: sinus infections ear infection
dalvyx [7]

The  immunization that is available to prevent communicable disease and illness is chicken pox.

Communicable diseases are diseases that can easily spread from person to person especially through contact with infected persons. Immunization is the process of preventing the spread of diseases by giving vaccines.

A common communicable disease is chicken pox. Hence, the  immunization that is available to prevent communicable disease and illness is chicken pox.
