Which of the following statements about Telomeres is NOT true? Telomere repeat sequences are determined by the RNA sequence in the Telomerase riboprotein. Telomerase extends one strand of the chromosome end. DNA polymerase is then required for synthesis of the other strand. Telomerase has an RNA-dependent DNA polymerase activity – meaning that it can synthesize DNA using an RNA template. Telomerase is a riboprotein, meaning that it has both RNA and protein components. Unlike DNA polymerase, Telomerase is able to synthesize DNA in the 5' to 3' direction.
