What are the major differences between a prokaryotic cell and a eukaryotic cell?
Expert Solution & Answer
Summary Introduction
To review:
The differences between prokaryotic and eukaryotic cell.
Introduction:
The key difference between the prokaryotes and eukaryotes is known to be the most vital difference between the groups of various organisms. The eukaryotic cells comprisemembrane-bound structures like the nucleus, whereas the prokaryotic cells do not consist of this. The differences among prokaryotic and eukaryotic cellular structure also includes the presence of the cell wall, mitochondria, chloroplasts, and the chromosomal DNA (deoxyribonucleic acid) structure.
Explanation of Solution
| Eukaryotic cell | Prokaryotic cell |
| Nucleus is present. | Nucleus is absent. |
| Chromosomes are more in number. | Only one chromosome is present, which is not a true chromosome and is known as plasmids. |
| It is multicellular. | Unicellular. |
| The truemembrane-bound nucleus ispresent in it. | It is absent. |
| Animals as well as the plants are classified as the eukaryotic cells. | Bacteria and archaea are eukaryotic cells. |
| Meiosis as well as the fusion of the gametes leads to the recombination of genes | Partial recombination. |
| Lysosomes and peroxisomes are present. | It is absent. |
| Microtubules are present. | It is rare or absent. |
| Mitochondria are present. | Absent. |
| Histones wrap the DNA. | Multiple proteins work together to fold and wrap the DNA. |
| Large ribosomes. | Small ribosomes. |
Conclusion
Therefore, it can be concluded that eukaryotic and prokaryotic cells are different from one another and the prime difference is the structure of the two cells.

engineered constructs that consist of hollow fibers are acting as synthetic capillaries, around which cells have been loaded. The cellular space around a single fiber can be modeled as if it were a Krogh tissue cylinder. Each fiber has an outside “capillary” radius of 100 µm and the “tissue” radius can be taken as 200 µm. The following values apply to the device:R0 = 20 µM/secaO2 = 1.35 µM/mmHgDO2,T = 1.67 x 10-5 cm2/secPO2,m = 4 x 10-3 cm/secInstead of blood inside the fibers, the oxygen transport and tissue consumption are being investigated by usingan aqueous solution saturated with pure oxygen. As a result, there is no mass transfer resistance in the synthetic“capillary”, only that due to the membrane itself. Rather than accounting for pO2 variations along the length ofthe fiber, use an average value in the “capillary” of 130 mmHg.Is the tissue fully oxygenated?

You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold
6. Mutations in the promoter that prevent binding of RNA polymerase
7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase

Please help and there is an attached image. Thank you.
A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter.
A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.

- You have returned to college to become a phylogeneticist. One of the first things you wish to do is determine how mammals, birds, and reptiles are related. Like any good scientist, you need to consider all available data objectively and without a preconceived “correct” answer. In pursuit of that, you should produce a phylogenetic tree based only on morphological features that show birds and mammals are more closely related. You will then produce a totally different tree, also using morphological features, that shows birds and reptiles are more closely related. Do not forget to include all three groups in both your trees. Based solely off the trees you produce, which relationship would you consider the more likely and why? Once you have answered that question, provide a brief summary of the “modern” understanding of the relationship between these three groups.arrow_forwardtrue or false, the reason geckos can walk on walls is hydrogen bonding between their foot pads and the moisture on the wall.arrow_forwardBiology laboratory problem Please help. thank you You have 20 ul of DNA solution and 6X DNA loading buffer solution.
