Document Summary
Additional dna on the chromosomes so that when it divides the actually piece of dna that is replicated isn"t destroyed. However when the chromosomes divide to much then a hayflick limit will determine when it will actually start to shorten your dna due to no more telomeres. Somatic cells don"t have the ability to prolong their telomeres. Look for specific sequence, when they find it they will cut. Can help express different genes in the genome. And insert a piece of dna into a plasmid. To able to pick a portion of dna and start with a low amount of dna and end up with a large amount of dna with a specific area. Some cells divide very often (roots, epithelium, etc) Some do not divide in adults (red blood cells, muscles, most neuron) G1: growth getting ready for dna to be replicated.
