Option A, B, C, D and E

Its activity can also be turned off leading to continuous shortening during replication and bringing about senesence and aging. the T-loops formed by the activity of the telomerase protects the ends of the chromosomes from being recognized as being broken and degradation.
DNA contains the blueprint for producing the whole organism.
