How can mutations in noncoding segments of dna contribute to the development of cancers?

Explanation:

Several mutations have been shown to be connected to the development of cancer. Mutations in the front area of the gene which controls the length of telomeres, can trigger cancer. Telomeres decide how many times a cell can divide and every time a cell divides the telomeres becomes shorter meaning at a stage the telomeres are so short that the cells can not longer divide. However, when mutation occurs in the region before the gene it makes it active and extends the length of telomeres in an abnormal way making cells to keep dividing itself leading to a tumour.

Also when mutation and replication occurs in non coding regions, it leads to copying of unwanted genes that will alter the protein structure and thus leads to a disease condition and even cancer.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
