Question

Which of the following is TRUE regarding telomerase?

A) Telomerase allows for extension of the lagging strandtemplate stranaheis
B) Telomerase is needed due to a gap that remains from lagging
C) Telomerase is normally inactive in adult somatic cells
D) Telomerase contains a built-in RNA template.
E) all of the above strand/template strand of DNA strand synthesis.

Answer 1

D) Telomerase contains a built-in RNA template.

Step-by-step explanation:

Telomerases are enzymes that catalyze the addition of telomeric DNA sequences, preventing DNA loss and thus helping to maintain genome integrity.

Telomerase is a specialized reverse transcriptase as it produces DNA from an RNA template strand. The RNA template chain is one of two components that make up telomerase, that is, it is incorporated into its structure. The other component is a protein with catalytic activity. The RNA and protein component of telomerase make this enzyme a ribonucleoprotein.

With this, we can conclude that the letter D is the correct alternative.
