The process of translation in prokaryotes can occur faster than in eukaryotes because
Nimfa-mama [501]

Answer:

Transcription and translation occur simultaneously in prokaryotes.

Explanation:

Prokaryotes lack membrane-bound organelles and therefore, do not have a nucleus. Transcription and translation occur in the cytoplasm. As soon as the required length of mRNA is being formed, ribosomes join it and start the process of translation. Prokaryotic genes lack introns. The primary transcript formed by transcription in prokaryotes does not undergo splicing.

On the other hand, the process of transcription occurs in the nucleus in eukaryotes while translation occurs in the cytoplasm. The primary transcript formed by transcription in eukaryotes undergoes modifications to remove introns and to add a poly-A tail and 5' cap. Post-transcriptional modifications and spatial separation of two processes in eukaryotes result in slower translation than prokaryotes.

Antibiotics, such as penicillin, are drugs that kill or prevent the growth of bacteria. When antibiotics were first discovered,

Cool topic you're learning about. Antibiotic resistance occurs because of the fact that bacteria change in response to the use of medicaments, such as penicillin. The problem about antibiotic resistance, an international health crisis, is that people OVERDOSE in medicaments. Antibiotics are known to kill weak and sensitive bacteria, but some resistant bacteria grow and multiplicate, since they know how the medicament works.

Therefore, I would say that bacteria that are not initially killed by the antibiotic,  they go to reproduce passing the resistance on to offspring. Antibiotic resistance is a big example when it comes to natural selection.
