Telomere and telomerase. Illustration showing how the enzyme telomerase (blue) acts on a telomere,the endpoint of deoxyribonucleic acid (DNA) found in chromosomes. The telomere is a region of repeated non-coding nucleotides (green),the function of which is to prevent coding nucleotides being lost during DNA replication. Telomeres shorten over time and this process is thought to play a role in cancer and ageing. Telomerase is a reverse transcriptase that creates the telomere regions using an RNA template (yellow). The nucleotides are A (adenine),C (cytosine),G (guanine),and T (thymine). For this artwork without labels,see C023/8863 | |
