Abnormal chromosomes are frequently found in malignant tumors. Errors such as translocations may place a gene in close proximity to different control regions. Which of the following might then occur to make the cancer worse? A) an increase in nondisjunction B) expression of inappropriate gene products C) a decrease in mitotic frequency D) death of the cancer cells in the tumor

B) expression of inappropriate gene products

Explanation:

Most of the cancers are caused when a normal gene that code for one or other proteins involved in the regulation of the cell cycle is mutated. The mutated gene may cause the production of the faulty gene products. For example, the overproduction of products of the protooncogene that push cells through the cell cycle leads to tumor formation. Likewise, when the tumor suppressor genes are not able to produce enough product to prevent progression through the cell cycle, cancer may develop.

the answer to your question is:

c. complementary base-pairing

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
