DNA is transcribed to make mRNA.
The mRNA is edited and transported to the cytoplasm, where ribosomes (including rRNA) bind to the message.
tRNAs bearing amino acids migrate to the ribosome, and those with the appropriate anticodon bind to the mRNA. The ribosome attaches the amino acid from the tRNA to the growing protein.

PROTEIN SYNTHESIS This procedure may nicely be divided into 2 factors: a million. Transcription earlier the synthesis of a protein starts, the corresponding RNA molecule is produced by technique of RNA transcription. One strand of the DNA double helix is used as a template by technique of the RNA polymerase to synthesize a messenger RNA (mRNA). This mRNA migrates from the nucleus to the cytoplasm. in this step, mRNA is going via sorts of maturation which includes one observed as splicing even as the non-coding sequences are eliminated. The coding mRNA sequence may nicely be defined as a unit of three nucleotides observed as a codon. 2. Translation The ribosome binds to the mRNA on the start codon (AUG) it quite is known purely by technique of the initiator tRNA. The ribosome proceeds to the elongation element of protein synthesis. in this degree, complexes, composed of an amino acid linked to tRNA, sequentially bind to the suitable codon in mRNA by technique of forming complementary base pairs with the tRNA anticodon. The ribosome strikes from codon to codon alongside the mRNA. Amino acids are added one by technique of one, translated into polypeptidic sequences dictated by technique of DNA and represented by technique of mRNA. on the best, a launch element binds to the best codon, terminating translation and liberating the entire polypeptide from the ribosome.

didn't you already ask this question in biology? didn't i already answer this question?...i'm sorry, i just get frustrated when questions are repeated
