Telomerase is involved in adding DNA to the end of the lagging strand.

Telomerase maintains the telomeres of chromosomes in order to prevent cell death. This enzyme added sequences onto the ends of the chromosomes, thereby preventing extreme shortening and loss of genetic material. In a way, telomerase would give cells immortal life, by continuously regenerating its ends. However, telomerase are usually inactive in the human body because normal cells do not divide frequently, and therefore, the chromosomes do not shorten.

Telomerase function is to protect the chromosome ends. This protein binds to the ends of the chromosomes solving issues with DNA end replication
