Which of the following best describes why ends of linear chromosomes cannot be replicated comepletely?
A) Telomeres are heterochromatin; therefore, no replication of the telomeres even occurs
B) Nucleotides on the 5' end of a DNA strand (template) cannot be replicated because there is no binding site for a primer, which is required by DNA polymerases
C) The 5' end of a DNA strand (template) cannot be replicated because DNA polymerase cannot add nucleotides on to the 5' end
D) Nucleotides on the 3' end of a DNA strand (template) cannot be replicate becaue there is no binding site for a primer, which is required by DNA polymerases
