Popis: The difference in optimal conditions for DNA polymerization catalyzed by AMV reverse transcriplase on poly(A) and poly(dA) templates with d(pT)10 and (pU)10 primers has been found. A comparison of the initiating abilities of d(pT)10 and (pU)10, primers under optimal conditions for various template · primer complexes has been made. The best template · primer complex was poly(A) · d(pT)10 and the worst was poly(A) · (pU)10. The lengthening of d (pT)n primers by a mononucleotide unit (n=2 10) increases their affinity by a factor of about 2 and 3 in the case of poly(dA) and poly(A) templates, respectively. The affinities ofd (pT)11–25 to the enzyme does not change with the primer length.
