Coding for proteins?

which sequences of dna don't code for proteins?Coding for proteins?
On a simple level, non-coding DNA does not code for proteins and only genes code for proteins.





In eukaryotes, such as humans, a large percentage of DNA is non-coding. Some non-coding DNA regulates the activity of coding regions, however much of it has no known function and is therefore referred to as ';junk DNA';





Junk DNA is mostly made up of repetitive elements, such as minisatellites, microsatellites, SINEs (short intersperced elements) and LINEs (long intersperced elements).





In addition to junk DNA, introns don't code for proteins.Coding for proteins?
DNA is a protein that has sequences of genes which act as a roadmap/instruction manual for other proteins to form organs, tissues, etc.


If you're looking for particular gene sequences, you're probably asking this question in the wrong place, unless there are a couple of PhD's from the human genome project hanging around on this site.


Now get back to work on that thesis...LOL
Ok wait...I rethought your question. It sounds like you are referring to introns....the sections of mRNA that are non-coding. They are spliced out so that only exons remain, and these are the sections of mRNA that are transcribed to the protein.
the y is always first
