In a nucleus, the number of RNA nucleoside triphosphates is 10 times more than the number of DNA nucleoside triphosphates, still only DNA nucleotides are added during the DNA replication, and not the RNA nucleotides. Why?

DNA polymerase is highly specific to recognise only deoxy ribonucleoside
triphosphates. Therefore it cannot hold RNA nucleotides.
