100% Correct Answers
You have a cell line that does not have density-dependent inhibition. You mutate a receptor for
brain-derived growth factor in the cell line. The mutation makes the receptor take the shape it
would be in if the growth factor were bound to the receptor. In other words, the receptor
becomes an oncogene. Compared to cells of this line without the mutation, the cells with the
oncogene would...
a) stay in G1 phase at the G1 checkpoint.
b) start making gametes instead of more of the same type of cells.
c) divide more frequently than usual.
d) divide until they touched each other, then stop.
e) stop dividing. divide more frequently than usual.
Sister chromatids separate from each other during
a) prophase II
b) prophase I
c) anaphase I
d) telophase I
e) anaphase II anaphase II
When in the life cycle do cells go from being haploid to being diploid?
a) when gametes are made in the gonads
b) during the mitotic cell cycle
c) during growth and development of the muscles and skeleton
d) during fertilization
e) during the meiotic cell cycle during fertilization
The purpose of mitosis is
,a) to get exactly one copy of each chromosome to each daughter cell.
b) to duplicate the DNA during cytokinesis.
c) to remove DNA that was damaged by mutations.
d) to get exactly two sister chromatids to each daughter cell.
e) to check for damage to the DNA. to get exactly one copy of each chromosome to each
daughter cell.
Where does fertilization normally take place?
a) in the oviduct
b) in the uterus
c) in the cervix
d) in the vas deferens
e) in the ovary in the oviduct
During telophase of mitosis, the chromosomes
a) condense.
b) duplicate.
c) form one circular chromosome.
d) line up in the middle of the cell.
e) uncoil from their condensed state. uncoil from their condensed state.
Prokaryotic cells divide by
a) binary fission.
b) metastasis.
c) cytokinesis.
d) mitotic cell division.
e) translation. binary fission.
, When there are mistakes in the replication of DNA during the mitotic cell cycle, the cell is most
likely going to
a) stop at the G2 checkpoint.
b) divide more rapidly than usual.
c) eliminate the defective chromosomes from the cell and continue dividing with only the non-
mutated chromosomes.
d) stop at the M checkpoint.
e) stop at the G1 checkpoint. stop at the G2 checkpoint.
You are studying cells where the number of types of chromosomes (n) is equal to seven. You
look down the microscope and see one cell with seven duplicated chromosomes lined up on
the metaphase plate. This cell is in
a) metaphase I of meiosis.
b) prophase I of meiosis.
c) metaphase II of meiosis.
d) metaphase of mitosis.
e) anaphase of mitosis. metaphase II of meiosis.
During the mitotic cell cycle the cytoskeleton does NOT
a) make cells divide by cytokinesis.
b) make the cell elongate.
c) pull on the duplicated chromosomes, so that they line up on the metaphase plate.
d) pull the sister chromatids apart.
e) duplicate the chromosomes, replicating the DNA. duplicate the chromosomes, replicating
the DNA.
Which part of the female reproductive system is where meiosis occurs?
a) All of the other answers are correct.
