Final answer:
If a chromosome is broken in the middle of two telomeres, the portion lacking a "telomere" will be lost from the cell lineage and will not be passed to descendant cells.
Step-by-step explanation:
Telomeres, which are the ends of linear chromosomes, protect the genes from getting deleted as cells continue to divide. If a chromosome is broken at the position in the middle of two telomeres, the portion lacking a telomere will be lost from that cell lineage and will not be passed to descendant cells. Telomeres consist of repetitive sequences and are added to the ends of chromosomes by the enzyme telomerase. When telomerase attaches to the end of the chromosome, DNA nucleotides complementary to the RNA template are added on the 3' end of the DNA strand, replicating the ends of the chromosomes.
