Guida verificata passo dopo passo1
Understand that eukaryotic chromosomes have specialized structures at their ends called telomeres.
Recognize that telomeres consist of short, repetitive sequences of non-coding DNA.
Recall that the primary function of telomeres is to protect the ends of chromosomes from deterioration or fusion with neighboring chromosomes.
Differentiate telomeres from other DNA structures such as centromeres, which are involved in chromosome segregation during cell division, and exons and introns, which are parts of genes involved in coding and non-coding sequences respectively.
Conclude that the short repeats of DNA found at the ends of eukaryotic chromosomes are known as telomeres.
