Ramirez 1 Alma Ramirez Professor Stewart Physiology 1 23 June 2019 Transcription Transcription is the first stage in the central dogma, this makes a copy of a particular stretch of DNA also known as gene, this process happens within the nucleus. Transcription takes place in the cells nucleus if DNA leaves the nucleus it could get destroyed. Not only could DNA get destroyed but it is double stranded and not be able to fit the nuclear pores. Since DNA can only be in the nucleus it needs an intermediate to do the work. This intermediate would be the RNA. RNA is single stranded, it leaves the nucleus through the nuclear pores and deliver the base sequence to ribosomes for protein synthesis. Transcription consists of three stages within this process which are the initiation, elongation, and termination. The process of transcription happens is in a sequential way. The first stage is initiation where the RNA polymerase is going to strike a very specific gene with specific sequence (AUG).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
