shortening of the telomere is like the fraying of a shoelace

An example of simile and metaphor in popular science writing"

"Every time a cell undergoes mitosis, it loses a little of what is called the telomere, the protective surface on the chromosome, capping the end of each D.N.A. strand. In a process often likened to the gradual fraying of a shoelace, the telomere gets a little shorter with every division, until eventually it can no longer guard the D.N.A. effectively, and the cell loses its ability to undergo mitosis and becomes senescent (inert)."
