During Mitosis, it isn't the nucleus itself that divides it is the chromatin inside the nucleus that duplicates during Prophase. This is so the new cells being created each have the correct amount of DNA for normal cell use.
Because the nucleus is like the center of the cell. It tells the cell what to do and basically controls it.

Why does transcription take place in the cytoplasm?
Transcription typically occurs in the nucleus of eukaryotic cells, where DNA is located, while translation takes place in the cytoplasm. However, in prokaryotic cells, transcription and translation occur simultaneously in the cytoplasm because they lack a defined nucleus. This proximity allows for a rapid response to environmental changes, as mRNA can be translated into proteins immediately after being synthesized. In eukaryotes, mRNA must first be processed and transported from the nucleus to the cytoplasm before translation can occur.
MRNA must pass through which membrane?
The nuclear membrane.In eukaryotic cells, DNA is transcribed into mRNA within the nucleus. Once transcription is complete the mRNA must exit the nucleus to be translated into protein, which ocurrs in the cytoplasm. Thus, mRNA must pass through the nuclear membrane.
What molecules must pass between nucleus and cytoplasm?
Molecules that must pass between the nucleus and cytoplasm include mRNA (messenger RNA), tRNA (transfer RNA), and proteins. These molecules play crucial roles in gene expression and protein synthesis within the cell.
Why must the nucleus of the unfertilized egg be destroyed before the parent cell's nucleus is inserted?
The destruction of the unfertilized egg's nucleus is necessary to prevent the formation of two separate sets of chromosomes in the resulting embryo. This ensures that the offspring will have the correct number of chromosomes for proper development by combining the genetic material from the parent cell with the donor's cytoplasm.
Why must you go through the process of changing DNA into rna?
In order to protect the DNA from potentially damaging reactions in the cytoplasm, the nucleus prevents the DNA from leaving it. Therefore it must be transcribed by mRNA, which can leave the nucleus.
List five organelles that must divide or fragment before the cytoplasm divides?
Mitochondria: As the cell prepares to divide, mitochondria divide to distribute equally in the daughter cells. Chloroplasts: In plant cells, chloroplasts undergo division to ensure each daughter cell receives a sufficient number. Endoplasmic reticulum: The endoplasmic reticulum fragments during cell division to distribute evenly in the daughter cells. Golgi apparatus: Golgi apparatus fragments into smaller units to be distributed in daughter cells during cell division. Nucleus: The nucleus undergoes division to ensure each daughter cell receives a complete set of genetic material.
In a cell information that controls the production of proteins must pass from the nucleus to the?
The information that controls the production of proteins must pass from the nucleus into the cytoplasm in the form of mRNA. mRNA is a template copy of the DNA inside the nucleus and is read by ribosomes in the cytoplasm to produce proteins.
What are 2 characteristics that that all organisms share?
All cells have to have two characteristics including the ability to grow. Cells must also have the ability to divide.
If a cell contains a nucleus it must be a prokaryote?
This statement is incorrect. Prokaryotic cells do not contain a nucleus. They have their genetic material located in the cytoplasm in a region called the nucleoid. Cells with a nucleus are eukaryotic.
MRNA must pass through which membrane?
The nuclear membrane.In eukaryotic cells, DNA is transcribed into mRNA within the nucleus. Once transcription is complete the mRNA must exit the nucleus to be translated into protein, which ocurrs in the cytoplasm. Thus, mRNA must pass through the nuclear membrane.

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.
Kind of a cell that does not have a nucleus?
Kind of cell that does not have a nucleus?
What must occur before RNA can leave the nucleus?
The RNA must have its introns (junk RNA) spliced out. It the must be processed by having a guanine cap and 100+ adenine tail added to it. Once all this is done, the now mature RNA can leave the nucleus to be translated.
Which process must occur before DNA information is moved out of the nucleus by mRNA?
Transcription must occur .
