Begin by understanding the structure of eukaryotic chromosomes. Eukaryotic chromosomes are linear DNA molecules that have specific regions with distinct functions.
Identify the different regions of a chromosome: telomeres, exons, introns, and centromeres. Each of these has a unique role in the chromosome's function and structure.
Telomeres are the regions located at the ends of eukaryotic chromosomes. They consist of repetitive nucleotide sequences that protect the chromosome from deterioration or fusion with neighboring chromosomes.
Exons and introns are parts of genes. Exons are coding regions that are expressed, while introns are non-coding regions that are removed during RNA processing.
Centromeres are the central part of a chromosome, crucial for the movement of chromosomes during cell division. They are not located at the ends of chromosomes.
