ABSTRACT
A definition of the term "telomere" is presented. It refers to a repetitive segment of DNA that is found on the ends of chromosomes. With each mitotic division, there is a loss of parts of the telomeres of a chromosome. According to a theory of cellular aging, the telomeres act as a biological clock and when they are depleted, the cell dies or becomes much less active.

    Over 60 years ago Barbara McClintock described the telomere and suggested that it protected the chromosome from illegitimate or end-to-end fusion, thus functioning to protect the genome. Since that time we have discovered that the telomere is a complex structure composed of both DNA and a...

    A definition of the term "terminal restriction fragments (TRF)" is presented. To measure the length of telomere, cellular DNA should be digested with restriction enzymes having 4-base recognition sites. They are non-palindromic and they lack restriction sites. TRF can be identified by probing...
