a quick question about insulin

Postby phanhuyen12 » Sun May 13, 2018 7:55 pm

Can someone please describe and explain the transcription of insulin gene,but it also include the formation of mRNA and triplet codes?

Hi, thank you for your question.

Since insulin is a polypeptide, a protein, it is genetically transcribed through a process that most other proteins undergo. The first stage of gene expression is transcription, in which the triplet codes of DNA (each triplet codon base codes for a specific amino acid) is transcribed to mRNA (if you'd like to learn more in depth details about DNA transcription, please visit: https://www.khanacademy.org/science/bio ... nscription ). Post transcription, the newly formed mRNA exits the nucleus and enters the cell's cytoplasm, where ribosomes will decode the mRNA to produce a specific amino acid sequence (if you'd like to learn more information about translation, please visit: https://www.nature.com/scitable/topicpa ... on-6523228 ). After termination, the completed polypeptides may undergo a few more molecular additions before finally being considered "finished" and fully capable of unfolding and performing their task (in this case, insulin synthesis is limited to production within the beta cells of the pancreas).

In order to familiarize yourelf with the 20 essential amino acids, it is best recommended to take a look at the standard amino acid chart: http://www.tritechresearch.com/shop/images/aachart.gif .

Hope this helps!
