Which of these statements is correct for this statement, which of the following best describes the function of telomerase? Option 1: It adds new DNA to the 3' end of the template strand Option 2; It synthesizes DNA without the use of a template Option 3: It adds new DNA to both strands of the telomere overhang Option 4: It adds new DNA to the 5' end of the newly synthesized strand

Telomerase is an enzyme that adds short, tandemly repeated DNA sequences to chromosome ends. Which of the following statements are true of telomerase? Select all that apply: 1. It adds DNA nucleotides to the 3' end of the 5'-> 3' parental strand. 2. It reads DNA as a template and synthesizes RNA as a product. 3. It is a ribonucleoprotein since it possesses both a protein and an RNA component. 4. It is active in most somatic cells in humans. 5. Its activity and telomere length have been linked to the aging process. 6. It is typically active in cancer cells. Please select which numbers apply.
Which of the following statements can be said about the enzyme telomerase? Select all the answers that apply: It exhibits reverse transcriptase activity. It is highly expressed in cancer cells. It shortens the ends of chromosomes. It extends the lifespan of cells. It removes RNA primers.
