Because mRNA is a single stranded molecule where as DNA forms a double helix. Therefore mRNA is a smaller molecule than DNA so can leave the nucleus
ALSO
mRNA has been processed post-translation. This means a 5' cap has been added and a 3' poly(A) tail has been added. This 5' cap, which DNA does not have, allows mRNA to leave the nucleus through nuclear pores.
All above is good idea all ,
And me have something that need to include more. First time DNA can't leave from nucleus ,so DNA change to be nucleotide then mRNA go into nucleus and duplication ,A , T, C, G of DNA to be U,A,G,C. During mRNA get out from nucleus , mRNA will go to ribosomes to produce protein to take care cell.
What else can I help you with?
What molecule cannot leave the nucleus?
Dna. Yet, surprisingly, any other molecule that I can think of may exit and enter.
What does mRNA stand for and why does it have to be made?
mRNA stands for messenger ribonucleic acid. It is essential for the process of protein synthesis as it carries the genetic information from the DNA in the cell nucleus to the ribosomes in the cytoplasm, where proteins are made.
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.
What organelle also stores DNA?
The nucleus contains most of the DNA in a cell and this DNA is called the chromosomal DNA. It is separated from the rest of the cell by a double layer of membrane. The mitochondria also contain DNA, called the mitochondrial DNA.
Why cant proteins be made directly from the DNA message and what is the middleman?
DNA does not leave the nucleus, and proteins are synthesized on the ribosomes in the cytoplasm and rough endoplasmic reticulum. The middleman is messenger RNA, or mRNA, which transcribes the DNA code in the nucleus and takes it to the ribosomes.
What molecule cannot leave the nucleus?
Dna. Yet, surprisingly, any other molecule that I can think of may exit and enter.
Why can't DNA leave the nucleus?
DNA cannot leave the nucleus because it is a vital molecule that contains important genetic information needed for the cell to function properly. The nucleus acts as a protective barrier to ensure that the DNA remains safe and undamaged. If DNA were to leave the nucleus, it could be exposed to harmful substances or processes that could potentially harm the cell.
Can DNA or RNA leave the nucleus?
Yes, both DNA and RNA can leave the nucleus. RNA regularly leaves the nucleus to carry out various cellular functions, while DNA can also leave the nucleus during processes like DNA replication and repair.
Does DNA ever leave the nucleus?
Yes, DNA can leave the nucleus during processes such as transcription and replication. However, the majority of DNA is typically contained within the nucleus of a cell.
Which one can leave the nucleus: DNA or RNA?
RNA can leave the Nucleus.
Does DNA or RNA leave the nucleus?
Yes, both DNA and RNA can leave the nucleus. RNA regularly leaves the nucleus to carry out various functions in the cell, while DNA typically remains in the nucleus except during cell division.
Can DNA or RNA leave the nucleus during cellular processes?
Yes, both DNA and RNA can leave the nucleus during cellular processes. RNA regularly moves out of the nucleus to carry genetic information to the cytoplasm for protein synthesis, while DNA can also leave the nucleus for specific functions such as DNA repair or gene regulation.
What is the term for DNA after it has left the nucleus?
The DNA found in the nucleus does not leave the nucleus. Instead, a copy of this DNA is carried on mRNA out of the nucleus and to the ribosomes. By keeping the DNA in the nucleus, it is protected from degradation - so a "master copy" of the instructions can be kept safe.
How does mRNA leave the the nucleus after copying DNA?
nucleic acids
What does mRNA stand for and why does it have to be made?
mRNA stands for messenger ribonucleic acid. It is essential for the process of protein synthesis as it carries the genetic information from the DNA in the cell nucleus to the ribosomes in the cytoplasm, where proteins are made.
If Dna cannot leave the Cell how can It get Its information out to the rest of the Cells?
DNA in the nucleus of a cell is responsible for producing messenger RNA (mRNA) molecules that carry genetic information to the cytoplasm, where it can be used for protein synthesis. These mRNA molecules act as messengers between the nucleus and the rest of the cell, ensuring that the genetic information encoded in DNA can be translated into functional proteins throughout the cell.
What molecule is able to leave the nucleus with the genetic code?
Perhaps you are talking about messenger RNA, mRNA, that is transcribed from DNA in the nucleus and leaves the nucleus to go into the cytosol where it docks with a ribosomal subunit where translation takes place.
