Here's why:
* Telomeres are protective caps at the ends of chromosomes. They are made of repeating DNA sequences and associated proteins. Their main function is to prevent the degradation of chromosomal DNA during replication.
* Protein-coding regions are called genes. Genes are located within the chromosome, but not at the ends where the telomeres are. Genes contain the instructions for building proteins.
Think of it like this:
* Chromosome: The entire book.
* Gene: A specific chapter within the book that contains instructions for making a specific protein.
* Telomere: The book cover that protects the pages from damage.
Telomeres are essential for maintaining the integrity of chromosomes and preventing DNA damage, but they do not contain the genetic information to build proteins.
