DNA polymerases are unable to replicate what areas of the chromosome?
A) Centromeres
B) 3' end of telomeres
C) Origins of replication

Question

Quizplus · Accepted Answer

DNA polymerases are unable to fully replicate the very end of the chromosome, known as the 3' end of telomeres. This is due to the inability of the enzyme to replace the RNA primer at the very end of the chromosome, resulting in a loss of genetic information in subsequent rounds of replication.
