What protects chromosomes from degradation and why?

Answer 1

Chromosomes are protected by telomeres.

Telomeres are repetitive sequences of nucleotides found at the tail end of each chromosome. Since the enzymes involved in DNA replication have difficulty replicating all the way to the end, chromosomes are frequently cut short during DNA replication. By adding a repetitive sequence of nucleotides, a buffer is created to ensure that no critical sections of the chromosome are inadvertently cut short.

Telomeres protect chromosomes from degradation by preventing the loss of genetic material during cell division. They act as protective caps, maintaining the structural integrity of chromosomes and ensuring accurate replication.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
