57. • The telomeres keep the ends of the chromosomes in the
cell from attaching to each other. When the replication
fork opens, DNA polymerase begins to synthesize strand
called Okazaki fragments. A DNA ligase stiches the
Okazaki fragments together. Telomerase is an enzyme
that adds telomere repeat sequences to the 3' end of
DNA strands. The crucial feature that distinguishes a
cancer from normal tissue is its ability to grow
indefinitely. Transplanted cells is when you take cells out
of the patient, then transform them with the gene for the
product that the patient has been unable to synthesize,
last return to the patient. The DNA strand was separated
then cloned into two more stands. Cellular aging is when
the cell becomes old. Incorrectly paired nucleotides can
become permant mutations. In eukaryote mutations can
lead to cancer.
