Actually I know what kind of process is Central Dogma, but the question is little bit confusing me. Below:?

The question is : I will pu tit directly


Below is a diagram of the “central dogma.” For each step (X, Y, Z) fill in the


following:


a) Name of the process


b) Name of the primary enzyme or enzyme complex


c) Template Macromolecule – the template read by the enzyme or enzyme


complex


d) Monomers polymerized –to form the new macromolecule


e) Initiation site – the name of the sequence in the template that directs the


enzyme to begin polymerization.


Can you give me some usefull siggestions how to answer?


I need to answer correctly since I didn't understand the question.Thank you very much for reading and replying for my question..

Actually I know what kind of process is Central Dogma, but the question is little bit confusing me. Below:?
First of all the "central dogma of biology" is that proteins are made as a result of specific DNA sequences (i.e. genes). So what the question is asking is to identify the steps of protein synthesis from transcription to translation.





So, transcription is the process by which DNA is read by RNA polymerases to form the mRNA. Translation is the process by which mRNA is read by ribosomes to form protein sequences, which are then folded into functional proteins.





Lets start with DNA to mRNA:


a) The process is transcription


b) RNA polymerase (there is an enzyme complex to this so check your notes for specifics)


c) Template macromolecule is DNA (specifically the template strand)


d) nucleotides (uracil, cytosine, guanine, adenosine)


e) hmm, it depends on if you are studying prokaryotic RNA transcription of eukaryotic RNA transcription. What are you studying? In prokaryotes it is the -35 and -10 promoter elements that trigger initiation.





So hopefully you get the gist of the question now. If you would like me to do mRNA to protein just post a new note.





Good luck.
