Which of the following is happening when translation takes place mRNA is still in the nucleus or DNA is being replicated?
When translation takes place, mRNA is used to synthesize proteins in the cytoplasm, not in the nucleus. Meanwhile, DNA replication occurs in the nucleus to create a copy of the genetic material before cell division. Translation and DNA replication are separate processes that occur in different cellular locations.
What are the differences in the process of translation between prokaryotes and eukaryotes?
In prokaryotes, translation occurs in the cytoplasm and can start before transcription is complete. In eukaryotes, translation occurs in the cytoplasm but the mRNA must first be processed and transported out of the nucleus before translation can begin. Additionally, eukaryotic ribosomes are larger and more complex than prokaryotic ribosomes.
Why do you stay in the nucleus to write down the mRNA?
The process of transcription, where mRNA is synthesized from DNA, occurs in the nucleus because that is where the DNA is located. The DNA serves as the template for mRNA synthesis, and enzymes and other necessary factors for transcription are also present in the nucleus. Additionally, keeping transcription and translation (where mRNA is used to make proteins) spatially separated allows for more control and regulation of gene expression.
What are the intervening sequence of RNA molecules that are cut out before the messenger RNA leaves the nucleus?
The intervening sequences of RNA molecules that are cut out before the messenger RNA leaves the nucleus are called introns. These introns are non-coding sequences that are spliced out of the pre-mRNA during the process of RNA splicing, leaving only the exons to form the mature mRNA that is then transported to the cytoplasm for translation.
What are three differences between transcription in prokaryotes and transcription in eukaryotes?
In prokaryotes, transcription occurs in the cytoplasm since they lack a nucleus, while in eukaryotes, transcription occurs in the nucleus. Prokaryotic transcription is often coupled with translation, meaning ribosomes can start translating mRNA even before transcription is complete, whereas in eukaryotes, transcription and translation are spatially and temporally separated. Prokaryotic mRNA does not typically undergo extensive processing (such as splicing or capping) after transcription, whereas eukaryotic mRNA is extensively processed before being translated.

Translation and DNA replication are separate processes that occur in different cellular locations.
In which organelle is DNA kept and RNA transcript?
DNA is kept in the nucleus, while RNA transcription occurs in the nucleus before the mRNA moves to the ribosomes in the cytoplasm for translation.
What are the differences in the process of translation between prokaryotes and eukaryotes?
In prokaryotes, translation occurs in the cytoplasm and can start before transcription is complete. In eukaryotes, translation occurs in the cytoplasm but the mRNA must first be processed and transported out of the nucleus before translation can begin. Additionally, eukaryotic ribosomes are larger and more complex than prokaryotic ribosomes.
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.
Does intron removal take place in the nucleus?
Yes, intron removal takes place in the nucleus. In eukaryotic cells, the process of RNA splicing, which involves the removal of introns from pre-mRNA, occurs in the nucleus before the transcript is transported to the cytoplasm for translation.
Where does the translation of secreted proteins take place?
The translation of secreted proteins takes place in the rough endoplasmic reticulum (ER) of the cell. After translation, the proteins are processed and modified in the ER before being packaged into vesicles for secretion outside the cell.
What is saddle point in nuclear fission?
In the liquid drop model, excitation energy in a nucleus gives rides to modes of motion or oscillations. On a potential energy surface, the saddle point corresponds to the critical deformation of unstable equilibrium in the nucleus.
What Before nucleus?
Prokaryotic cells don't have a defined nucleus.
How do you say Before leaving in French?
Before leaving is "avant de partir" in French.
What are cells called when they dont have a nucleus?
Prokaryote. Means; " before the kernel. " Which is literal Greek for before the nucleus.
What does before nucleus mean?
"Before nucleus" typically refers to the time period in a cell's history when it did not have a defined nucleus. This is known as the prokaryotic phase, where genetic material is not enclosed by a membrane-bound nucleus, as seen in organisms like bacteria.
Do I have to check out of the hotel before leaving"?
Yes, you typically need to check out of a hotel before leaving.
