A large ribosomal subunit bonds to the initiation complex. The codon adjacent to the initiation codon bonds to its complementary anticodon, which is part of a free tRNA. The two amino acids still attached to their tRNAs align. With the help of rRNA, amino acids form peptide bonds. Then, the first tRNA is released.
E. coli Primase Catalyzes Formation of RNA Primers for DNA Synthesis. As noted earlier, DNA polymerases can only elongate existing primer strands of DNA or RNA. The primers used during DNA replication in both prokaryotes and eukaryotes are short RNA molecules whose synthesis is catalyzed by the RNA polymerase primase.
