Why is protein synthesis different in prokatyke and euroaytes?
Prokaryotes do not have a distinct nucleus, so transcription and translation both occur in the cytoplasm simultaneously. In eukaryotes, transcription occurs in the nucleus while translation occurs in the cytoplasm, separated by nuclear envelope. Furthermore, eukaryotes have additional complexity due to post-transcriptional modifications and protein processing that prokaryotes lack.
Why is protein synthesis different in prokaryotes and eukaryotes Apex Learning?
Protein synthesis differs in prokaryotes and eukaryotes primarily due to their cellular structures. In prokaryotes, transcription and translation occur simultaneously in the cytoplasm, as they lack a defined nucleus. In contrast, eukaryotes have a compartmentalized structure where transcription occurs in the nucleus and translation takes place in the cytoplasm, allowing for additional processing of mRNA before it is translated. These differences reflect the complexity of eukaryotic cells compared to prokaryotic cells.
Why is protein synthesis different in pakaryotes and eukaryotes?
Protein synthesis differs in prokaryotes and eukaryotes primarily due to cellular structure and compartmentalization. In prokaryotes, transcription and translation occur simultaneously in the cytoplasm since they lack a defined nucleus. In contrast, eukaryotes have a nucleus where transcription occurs, followed by RNA processing before translation takes place in the cytoplasm. Additionally, eukaryotic mRNA undergoes modifications like capping and polyadenylation, which are not present in prokaryotic mRNA.
Does endocytosis occur in prokaryotes?
Yes, endocytosis does not occur in prokaryotes because they lack membrane-bound organelles and do not perform phagocytosis, pinocytosis, or receptor-mediated endocytosis like eukaryotic cells. Instead, prokaryotes rely on other mechanisms such as simple diffusion, facilitated diffusion, and active transport to take in nutrients and molecules.
Inhibitor of protein synthesis?
In prokaryotes tetracycline, chloremphenicol can inhibit protein synthesis. Puromycin is an antibiotic that inhibit both prokaryotic and eukaryotic protein synthesis. Each antibiotics has specific mode of action where it inhibits by binding, for example Chloremphenicol block the peptidyl transfer step.
Spherical prokaryotes that occur in chains?
Streptococci

Why is protein synthesis different in prokaryotes and eukaryotes?
In prokaryotes, DNA is stored in the cytoplasm. also prokaryotes have no nucleus In prokaryotes, transcription and translation happen at the same time.

Protein synthesis in eukaryotes and prokaryotes?
Protein synthesis occurs in cellular structures called ribosomes , found out-side the nucleus. The process by which genetic information is transferred from the nucleus to the ribosomes is called transcription. During transcription, a strand of ribonucleic acid (RNA) is synthesized.
Where does the process of making RNA from DNA occur?
nucleus for eukaryotes, cytoplasm for prokaryotes.

Does photophosphorylation occur in only prokaryotes?
No, photophosphorylation occurs in both prokaryotes and eukaryotes. It is a process in photosynthesis where light energy is used to phosphorylate ADP to ATP. In prokaryotes, it mainly occurs in the thylakoid membranes of the chloroplasts, while in eukaryotes, it occurs in the chloroplasts of plant cells.
Where does translation occure in prokaryotic?
In prokaryotes, the processes of transcription and translation occur simultaneously in the cytoplasm, allowing for a rapid cellular response to an environmental cue.
Post translational modification occurs in which cell organelle?
Post-translational modifications occur in the endoplasmic reticulum and Golgi apparatus, as well as in other cellular compartments. These modifications can include phosphorylation, glycosylation, acetylation, and more, which help to regulate protein function and localization within the cell.
When a cell needs to make a protein what two processes must occur and where does each of these occur?
Ribosomes make protein.
