Answer:

Provides both the RNA and the polymerase needed for synthesis

Explanation:

Telomerase is an enzyme which extends the telomere sequences present at the end of the chromosomes. The telomerase enzyme acts as DNA polymerase as well as provides the RNA which serves as a template strand rather than the primer.

The polymerase acts as a reverse transcriptase enzyme and synthesizes the DNA strand from the  RNA template. Since the telomerase provides RNA and acts as DNA polymerase, therefore, it is known as the ribonucleoprotein molecule.

Thus, the selected option is correct.

Answer:

Phosphorylation within the nuclear export signal interferes with the function of the  signal.

Explanation:

In biochemistry, phosphorylation is the addition of a phosphate group (PO4) to a protein or other molecule. Phosphorylation is a major player in protein regulation mechanisms, preventing protein-catalyzed reaction product from accumulating in the body causing problems.

However, in some cases phosphorylation may cause nuclear accumulation of a protein in the nucleus of the cell. An example of this is the protein shown in the question above. In this case, phosphorylation in the nuclear export signal interferes with the signal function, resulting in protein accumulation in the nucleus.
