96. The replication of the ends of linear eukaryotic chromosomes requires a specialized ribonucleoprotein complex called telomerase. The functional role of the RNA component within telomerase is to

A. Act as an enzymatic catalyst to link deoxyribonucleotides
B. Serve as an internal template for synthesizing telomeric DNA repeats
✓
C. Protect the chromosome ends from being recognized as double-strand breaks
D. Recruit the large ribosomal subunit to the nuclear matrix scaffold

📝 Explanation

Telomerase is a reverse transcriptase that carries its own internal RNA molecule to serve as a structural template for lengthening chromosome ends.
