DNA polymerases can only extend a DNA strand in a 5â² to 3â² direction, different mechanisms are used to copy the antiparallel strands of the double helix. In this way, the base on the old strand dictates which base appears on the new strand.
Just as in DNA replication, the enzyme reads the template strand in a 3ââ5â direction, while building the new RNA strand in a 5ââ3â direction. Again, two of the phosphate groups are removed as a new phosphodiester bond is formed, connecting the nucleotide to the chain.NA polymerase enzyme synthesizes a strand of RNA complementary to a section of one of the DNA strands (the template strand). 1. Initiation: A section of DNA known as the promoter (TATA box for eukaryotes) signals where the transcription begins. RNA polymerase recognizes and binds to this site.
