Molecular Genetics (The Basics)

A simplistic view of <The Central "Dogma" of Molecular Biology>:
A dogma is something that can never be changed. I put dogma in inverted commas because there is the existence of reverse transcriptase, with the ability to make cDNA (complementary DNA) from mRNA

My dear students,


Here are some videos to help you in understanding what exactly transcription is and what exactly translation is. 


Please note that for your syllabus, you do not need to know the whole transcription process. All you need to know is that mRNA is produced at the end of the transcription process and how you obtain this mRNA is through complementary base pairing with the template DNA strand.


However, you need to know the "simpler" translation process, how you obtain a polypeptide chain from an mRNA template. All the steps, I have listed down in the notes that I have already printed for you (and also uploaded as a .pdf onto AsknLearn). 


Thus, please use these videos to aid in your understanding, but do not stray away from what you really need to know at this point in time for your O levels. 


Yours truly,
Mrs Lehming
