Chain A   (Q0QHL8_TRICA | Q0QHL8)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0003964    RNA-directed DNA polymerase activity    Catalysis of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). Catalyzes RNA-template-directed extension of the 3'- end of a DNA strand by one deoxynucleotide at a time.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0003721    telomerase RNA reverse transcriptase activity    Catalysis of the extension of the 3' end of a DNA strand by one deoxynucleotide at a time. Cannot initiate a chain de novo; uses the RNA subunit of the telomerase enzyme complex as its template.
biological process
    GO:0006278    RNA-dependent DNA biosynthetic process    A DNA biosynthetic process that uses RNA as a template for RNA-dependent DNA polymerases (e.g. reverse transcriptase) that synthesize the new strand.
