Replication, Transcription, and Translation
... As new amino acids are brought to the ribosome, the growing peptide chain is attached to the new amino acid by a peptide bond. Elongation of the chain continues until a stop codon is encountered. At that point the peptide chain is released from the tRNA. A single mRNA can be read repeatedly to make ...

Replisome
The replisome is a complex molecular machine that carries out replication of DNA. The replisome first unwinds double stranded DNA into two single strands. For each of the resulting single strands, a new complementary sequence of DNA is synthesized. The net result is formation of two new double stranded DNA sequences that are exact copies of the original double stranded DNA sequence.In terms of structure, the replisome is composed of two replicative polymerase complexes, one of which synthesizes the leading strand, while the other synthesizes the lagging strand. The replisome is composed of a number of proteins including helicase, RFC, PCNA, gyrase/topoisomerase, SSB/RPA, primase, DNA polymerase I, RNAse H, and ligase.
