What is the role of di-deoxy DNTPs in a Sanger sequencing reaction? Please select the answer that is most correct. The di-deoxy DNTPs are incorporated into the growing DNA molecule. The di-deoxy DNTPs terminate polymerisation of the growing DNA molecule, thereby creating fragments which all end in that specific di-deoxy base. Subsequent separation of the fragments by size facilitates the ascertainment of the sequence. The di-deoxy DNTPs facilitate polymerisation of the growing DNA molecule. this allows for multiple copies fo the template to be made for further analysis. The di-deoxy DNTPs terminate polymerisation of the growing DNA molecule. Ending the replication ensures that the molecules are not too long to be sequenced.
