Question

Can you describe the flow of information from DNA in the nucleus to protein for me?

Answer 1

Yeah, sure.
DNA is copied by RNA polymerase and transformed into mRNA in a processes called Transcription. The copied strand is then modified in many ways including the addition of a 5' cap and a 3' Poly-Adonesinated Tail and the removal of Introns from the strand and the connection of the remaining Exons. Okay, these modifications allow the mRNA strand to exit the nucleus via the nuclear pores. The strand attaches to a floating ribosomes in the cytoplasm and begins to undergo a process called Translation. Translation is the process of reading the strand bit by bit (3 bases at a time, refereed to as a codon) and translates the three bases into their corresponding amino acid. The process begins when the AUG codon for the amino acid Methionine is translated and ends when the stop codons (UUG, UGA, UAG) are translated. The resulting poly-amino acid chain aligns and contorts itself based on its inherent electrical charges into the form of the protein that that exact sequence specifies. Wow, I hope that is what you were looking for. Best of Luck.

Answer 2

DNA gets translated into mRNA in the nucleus. mRNA travels into the cytoplasm and makes contact with a ribosome. The genetic code of the mRNA is transcribed into an amino acid sequence by tRNA. The amino acid sequence is the protein.

Answer 3

DNA is 'transcribed' in the nucleus into messenger RNA (mRNA). mRNA travels from the nucleus to the ribosomes in the endoplasmic reticulum where it is 'translated' into the appropriate protein.
