Mammalian chromosomes have specialized structures with highly repetitive DNA at their ends (telomeres). Which of the following aspects of telomeric DNA replication is different from that of other chromosomal regions?
1
The DNA polymerase uses an RNA primer but does not degrade it.
2
The DNA polymerase contains an RNA molecule that serves as template for DNA synthesis.
3
The DNA polymerase must cross-link the 5' and 3' termini.
4
The DNA polymerase has a subunit that facilitates binding to repetitive DNA.
