Mitosis is important for a number of reasons. It's a form of reproduction for some organisms that reproduce asexually, it's needed for growth and development, and also for the repair and replacement of cells. If we didn't do mitosis dead cells wouldn't be replaced, and that would cause some massive problems. For example, if we weren't capable of doing mitosis and you cut your hand, the cut wouldn't heal up because the cells wouldn't be getting replaced.
As can be understood, bacteria definitely help us live and thrive to be who we are today!
This is false. There are many factors, like climate, fires, pollution, etc.
Answer:
Protein production in prokaryotes begins even before the completion of transcription. This means that ribosomes attach to the mRNA being generated even before transcription process is terminated. Therefore translation occurs in concurrence with transcription. This is because there is no definitive boundary between the nucleoid and cytoplasm.
In eukaryotic cells, the nucleus is separated from the cytoplasm by the nuclear membrane. This means transcription has to complete before the translation of proteins occurs. This is because the ribosomes are located in the cytoplasm while the DNA is in the nucleus.
This difference is part of the reason prokaryotic cells are able to respond really fast to an environmental stimuli as compared to eukaryotes. Remember in addition mRNA in prokaryotes do not need splicing (as required in eukaryotes) adding to quick protein production.
