Before RNA can leave the nucleus, the DNA must be transcribed into a complementary mRNA molecule by the enzyme RNA polymerase. This mRNA is then processed, including the addition of a 5' cap and a poly-A tail, as well as the removal of introns through RNA splicing. Finally, the fully processed mRNA is able to exit the nucleus through nuclear pores and enter the cytoplasm for translation.

What event must occur outside the nucleus before mitosis can begin?
Before mitosis can happen, the chromosomes inside the nucleus must separate to form identical pairs. This sets the stage for each of the daughter cells to have a copy of the DNA to replicate the full sequence.
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 molecule cannot leave the nucleus?
DNA molecules cannot leave the nucleus. DNA carries genetic information and must remain protected within the nucleus to ensure the accurate replication and expression of this information.
Before condensation can occur what must be the relative humidity?
Before condensation can occur, the relative humidity must be 100%. This means that the air is saturated with moisture and cannot hold any more water vapor, resulting in it condensing into liquid.
What process must occur first before any cell division can takes place?
Before any cell�division to occur, everything must be duplicated. That occurs during inter-phase before mitosis or meiosis begins or occurs. Fertilization -apex-
Which process must occur before DNA information is moved out of the nucleus by mRNA?
Transcription must occur .
What event must occur outside the nucleus before mitosis can begin?
Before mitosis can happen, the chromosomes inside the nucleus must separate to form identical pairs. This sets the stage for each of the daughter cells to have a copy of the DNA to replicate the full sequence.
Does anything enter or leave the membrane-bound nucleus of animal cells?
Yes materials made inside of the nucleus such as ribosomes must leave
What must happen to the DNA before transcription can take place?
Before transcription can take place, the DNA in the cell nucleus must be unwound and separated into two strands by enzymes. This process exposes the genetic information that will be transcribed into mRNA.
What must occur before replication can?
the double helix must unwind
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.
Part of cellular respiration must occur before any of the other steps can occur?
.Glycolysis
What molecule cannot leave the nucleus?
DNA molecules cannot leave the nucleus. DNA carries genetic information and must remain protected within the nucleus to ensure the accurate replication and expression of this information.
What must always happen before a hypothesis can be formed?
a reveiw of what is known about the subject must occur
What must occur for diffusion to happen?
two molecules must collied before diffusion happens.
Before condensation can occur what must be the relative humidity?
Before condensation can occur, the relative humidity must be 100%. This means that the air is saturated with moisture and cannot hold any more water vapor, resulting in it condensing into liquid.
