Where does the central dogma occur and does it happen in every cell?

The central dogma occurs in the nucleus, endoplasmic reticulum and golgi apparatus before the end products are exported.
Does it happpen in every cell? The short answer is yes, but for a more comprehensive answer keep reading...
However in some cases it is believed that cells can skip the first step; ie. RNA makes protein. As far as I know this occurs in platelets. However platelet RNA was made from Megakaryocyte DNA. However platelets can apparently synthesize protein without having any cellular DNA, using only RNA as a template.
In addition, in the "RNA world theory" the idea is that RNA could have been the precursor to DNA as the cells information storage medium. In these theoretical ancestral organisms the dogma would be RNA makes RNA makes protein.

What is the importance of central dogma?
The central dogma of molecular biology was first enunciated by Francis Crick in 1958[1] and re-stated in a Nature paper published in 1970:[2] : The central dogma of molecular biology deals with the detailed residue-by-residue transfer of sequential information. It states that information cannot be transferred back from protein to either protein or nucleic acid. In other words, 'once information gets into protein, it can't flow back to nucleic acid.' The dogma is a framework for understanding the transfer of sequence information between sequential information-carrying biopolymers, in the most common or general case, in living organisms. There are 3 major classes of such biopolymers: DNA and RNA (both nucleic acids), and protein. There are 3×3 = 9 conceivable direct transfers of information that can occur between these. The dogma classes these into 3 groups of 3: 3 general transfers (believed to occur normally in most cells), 3 special transfers (known to occur, but only under specific conditions in case of some viruses or in a laboratory), and 3 unknown transfers (believed to never occur). The general transfers describe the normal flow of biological information: DNA can be copied to DNA (DNA replication), DNA information can be copied into mRNA, (transcription), and proteins can be synthesized using the information in mRNA as a template
When does annular eclipse happen?
The next annular solar eclipse will be on January 15, 2010. It will be visible from central Africa across the Indian Ocean to the southern tip of India, Sri Lanka, and across to central China.
The preparatory reactions occur how many times for every glucose molecule?
It occurs 2x per glucose molecules.. But the thing is, I didn't know how that happen
Do spring tides only occur in spring?
No, they occur every twice a month; every full moon and every new moon.
Do human feel most of the earthquakes that occur each year or very few?
Extremely few. Most earthquakes happen in the ocean, or too far below the crust for us to feel them, but hundreds happen every week.
How often does the Olympics occur?
The olympics happen every 4 years.
Where do most hailstorms occur?
Hailstorms can happen almost anywhere in the world. However, they are most likely to occur in the central plains and also the southern states.
Where did the London bombings happen?
The London bombing did occur in central London. The attack targeted the London Underground.
Do lunar eclipse occur ever 3 years?
No they happen every two years
What does not occur in cycles luner phases tides gravity or seasons?
The moon's phases happen every month. Tides happen twice a day. Seasons happen every year. So the only thing that doesn't happen in cycles is gravity.

What year will the eclipse happen?
The next total eclipse will occur on July 22 2009 in India, Nepal, China and central Pacific.
What happen if meiosis did not occur to produce sex cells?
the chromosome number would double in every generation
Will there be a tornado?
There will certainly be tornadoes in the future, hundreds of them happen every year. But there is no way of knowing exactly where or when they will occur.
What would happen if meiosis did not occur to produce sex cells?
the chromosome number would double in every generation
How many summer olympic occur in a year?
The summer Olympics happen every FOUR YEARS so does the winter
Were do the worst tornadoes occur?
Most of the worst tornadoes happen in the central and southern United States, though the worst single tornado on record was in Bangladesh.
