Answer 1

Hi mate.

Thanks for asking this question.

Here is your answer.





$eukryotic \: gene \: regulation \: steps$



Regulation of the eukaryotic gene involves many steps,.,. Different gene are regulated at different places and it is not a specific point to the specific gene.



(1) Chromatin accessibility :


Chromatin is a structure consists of the DNA and its organizing proteins can be regulated. The Chromatin makes the gene available for the process of transcription.


(2) Transcription :


Transcription is regulatory point for gene. Sets of the transcription factors proteins binds or attached to the coding sequence of the DNA and promote or suppresses its transcription in RNA.


(3) RNA processing :


By the means of alternating splicing, the different mRNA are produced from pre - mRNA. It involves the splicing, capping and additions to the poly-a tail on the RNA molecules.


(4) RNA stability :


In the life cycle of the mRNA the cytosol affects on the production of the proteins. Small regulatory RNA is known as miRNA. Which attached to the target mRNA.


(5) Translation :


Increase/ decrease in the translation of the mRNA Is totally dependent on the factors. miRNA sometimes blocks the translation of the mRNA.


(6) Protein activity :


By chopping or with the chemical groups the proteins undergoes in numbers of modifications. These modifications can regulates the behavior of the proteins.




Thank you.
