PG. 110
3) How are amino acids linked together to form three-dimensional polypeptide chains?
4) How does the study of bacteria cells help us understand how protein synthesis works in human cells?
7) How does slime mold help scientists understand how genetic control systems work?
9) What is the mechanism that causes cancer and what are its causes?
Explanation / Answer
9. Cancer-one cell gets a genetic mutation that turns on an oncogene or turns off a tumor suppressor gene and starts dividing faster than usual. Then, its descendants accumulate other mutations, including those in oncogenes or tumor suppressor genes and divide without restraint. Tumor suppressor genes usually encode for proteins that start apoptosis in abnormal cells while oncogenes promote cell division. Its causes include many things that damage cells, induce a faster rate of proliferation, or mutates genes. -- 3. Our bodies recognize nucleotide codes in sets of 3. or codons. Each group of three nucleotides codes for a different amino acid. During translation, the amino acids that correspond to the genetic sequence are polymerized into the proteins that the genes code for by a polymerase. 5. When DNA mutates, the proteins that they code for also mutate, sometimes into proteins that do not function properly. When the correct gene is inserted, that gene also gets translated inside the cell into the properly functioning protein, thus restoring normal function in the person with the genetic disorder. --
