Transcription is where a strand of DNA is copied for protein synthesis using messenger RNA (mRNA). This is the first step of central dogma. Through transcription, DNA is transferred to mRNA in the nucleus. The mRNA then take the code into the cystoplasm for protein synthesis.
Translation is the process in which mRNA attaches to the ribosome and a protein is assembled.
Replication is the process of duplicating or replicating DNA.
Polymerase connects to the DNA double-helix and uncoils it. Free nucleotide triphosphates are floating in the cytoplasm and RNA Polymerase connects them to the antisense strand by removing the phosphates and creating nucleotides. The nucleotides are added to the complementary bases where cytosine attatches to guanine, uracil connects to adenine, guanine connects to cytosine and adenine connects to thymine. Nucleotides keep binding to form an mRNA strand and then its released and the RNA Polymerase separates.
The mRNA strand binds onto the ribosome. A tRNA molecule with the complementary anti-codon to the start codon then attaches to the ribosome. The ribosome goes along the mRNA strand until it reaches the start codon. A codon is a 3 base code in DNA and RNA. When the ribosome reaches the start codon, another tRNA molecule connects to the ribosome. After the first codon is translated, the large sub-unit slides over the small sub-unit and binds. It forms a peptide bond between the two amino acids on the tRNA molecules. The tRNA molecule that translated the codon, separates from the ribosome and the small sub-unit slides back under the large sub-unit. Another tRNA molecule then attaches to the ribosome and the process repeats until the ribosome reaches the terminator which is also translated. After the terminator is translated, the ribosome sub-units detach from each other and the polypeptide chain detaches from the tRNA molecule. The polypetide chain is the new protein.
