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.
C-DNA polymerase catalyzes the formation of a phosphodiester bond between the 5â² phosphate of one nucleotide and the 3â² hydroxyl on the incoming nucleotide; therefore, chain growth is said to occur in the 5â² arrow 3â² direction. DNA polymerases are enzymes that copy: A. DNA into DNA. B. DNA into RNA.
