mRNA(messenger RNA)
The master copy of an organism's genetic code is the DNA.
mRNA (messenger) - copies DNA's code during transcription and carries it out of the nucleus and to the ribosome. tRNA (transfer) - binds to specfic amino acids, and carries them to the ribosome during translation rRNA (ribosomal) - makes up ribosomes
It is a direct - and exact - copy of the Genetic Sequence of the Dna; except that the base Thymine in Dna is replaced by the base Uracil in Rna.

Basically, mRNA carries a message away from the nucleus. The nucleus says hey, we need these proteins made, and mRNA is made by using RNA polymerase to copy the information on DNA. That mRNA then moves out of the nucleus to a ribosome, where rRNA and tRNA will interact with the mRNA, eventually resulting in the production of a fully functional protein.
mRNA carries a copy of our DNA, our genetic information and is used in the synthesis of these proteins.
There could be a mutation in the genetic code that controls cell reproduction.

RNA
DNA doen't leave the nucleus but a copy of the segment (called mRNA) that codes for the protein leaves the cell and meets up with a ribosome. The ribosome will translate the copy of the DNA into a specific protein.
Messenger RNA carries a copy of DNA out of the nucleus and into cytoplasm. Transfer RNA then carries amino acids to the copy of DNA to form a protein chain.
enzymes in the nucleus copy genes from DNA to messenger RNAsmessenger RNAs migrate from the nucleus through the cytoplasm to the ribosomesribosomes bind the messenger RNAs and transcribe them to proteins using transfer RNAs, each carrying one amino acidas the protein leaves the ribosome and enters the cytoplasm it folds into its final form, if necessary enzymes add crosslinks to lock the form perminantly
chromatid
DNA nucleotides 'code' for RNA copies of the DNA strand, but the true 'coding' of nucleotides happen in the ribosome where amino acids are matched to the RNA nucleotides. Nucleotides in DNA are only are present to store genetic data. When a particular gene needs to be used or a protein needs to be made, a RNA copy of the DNA will be made, using the slightly different RNA nucleotides (adenine, uracil, cytosine and guanine). This copy then leaves the nucleus and travels to the ribosome, where the RNA nucleotides are used to assemble amino acids into proteins. Each amino acid matches up to a three-nucleotide sequence.
