Which of the following statements concerning cancer cells is most accurate?
a. Proto-oncogenes are part of the regulatory section of a chromosome.
b. Tumor cells have lost their ability to stop dividing.
c. Proto-oncogenes help control runaway cell division.
d. Benign tumor cells usually spread only to adjacent organs.
e. Metastasis is the spread of benign cells.
I think it's B.
ERBB2 is a
a. type of membrane receptor
b. proto-oncogene
c. gene on chromosome 17
d. gene that mutates causing a tpe of breast cancer
e. gene that may be over-expressed resulting in a type of breast cancer.
I thought a, b, c, & d were all right....so I went with D.
The snipping out of specific introns for troponin production by muscle cells is an example of what type of gene expression control?
a. transcriptional
b. transcript-processing
c. transcript transport
d. translational
e. post translational
I thought it was B.
The conversion of proteins by the removal of a protein of polypeptide chain is an example of
a. transcriptional control
b. transcript processing control
c. transport control
d. translational control
e. post-translational control
I thouht it was B
Translational controls of gene expression affect
a. initiation factors
b. ribosome components
c. mRNA stability
d. mRNA longevity
e. all of these
I thought it was E
The development of organisms is based on
a. which genes are active in a given cell
b. when the genes function
c. what gene products appear
d. the amount of cellular products generated
e. all of theses
I thought it was E.
I've been seraching through countless books and websites, yet I can't find these answers. Any help would be appreciated!
