Quizplus · Accepted Answer

Telomeres are necessary because they maintain the length of a chromosome during replication. DNA is shortened each time it is replicated, so telomeres provide a buffer to protect important genetic information from being lost. Without telomeres, chromosomes would gradually become shorter and eventually might lose important genetic information.
