Question

researchers refer to telomerase as a
ibonucleoprotein.\ why is this term logical?
telomerase is part of the ribosome, which contains other proteins as well, and functions in translation.
telomerase synthesizes rna and is made entirely of protein.
telomerase has both rna (ribonucleic acid) and protein components.
telomerase is not the only example of
everse transcription.\ the genomes of many viruses—including hiv—are made of rna. after infecting a human cell, the viral genes are converted to dna, which then integrates into a host cell chromosome. viruses like these contain one or more reverse transcriptase proteins, which enter the cell along with the viral genes.
based on this information, what does this viral enzyme do? choose the single best answer.
makes a viral mrna from the viral genes.
makes a dna copy of the viral (rna) genes.
cuts the host cell chromosome and inserts the viral dna.

Explanation:

For the first question:

• A ribonucleoprotein is a complex of RNA (ribonucleic acid) and protein. Telomerase has both RNA and protein components, so the term "ribonucleoprotein" is logical for it.
• Telomerase is not part of the ribosome (the first option is wrong). And it is not made entirely of protein (the second option is wrong).

For the second question:

• Reverse transcriptase is an enzyme that performs reverse transcription. Reverse transcription is the process of making DNA from RNA.
• The first option is about making mRNA from genes (transcription, not reverse - transcription). The third option is about inserting DNA (not the function of reverse transcriptase).

Answer:

First question: Telomerase has both RNA (ribonucleic acid) and protein components.
Second question: Makes a DNA copy of the viral (RNA) genes.
