Exam Questions and CORRECT Answers
The two new daughter cells will be haploid, but the DNA they contain is still replicated. The
homologous chromosomes have separated and are ready to start the second division, but they
have not yet begun the second round of division.
Which stage of the cell cycle is this cell in? - CORRECT ANSWER - Telophase I
Homologous pairs of chromosomes have separated into two cells. Sister chromatids in each cell
have not yet lined up in the middle of the cell.
Which stage of the cell cycle is this? - CORRECT ANSWER - Prophase II
Which type of cell division results in sex cells? - CORRECT ANSWER - Meiosis
Which characteristic describes both meiosis and mitosis? - CORRECT ANSWER - Sister
chromatids separate
How is DNA structured during the metaphase stage of mitosis? - CORRECT ANSWER -
The centromere at the center keeps DNA lined up at the cell's equator.
What is true regarding the transition from metaphase to anaphase during mitosis? - CORRECT
ANSWER - Sister chromatids are aligned along the center of the cell and then pulled apart
into separate chromatids.
Which stage of mitosis is depicted? - CORRECT ANSWER - Prophase
Sister chromatids are being separated and moving towards opposite poles of the cell.
, Which stage of mitosis is this? - CORRECT ANSWER - Anaphase
Chromosomes are structures that contain hereditary material that will be passed from one
generation to the next.
According to this information, which organic molecule must be present in chromosomes? -
CORRECT ANSWER - DNA
A cell has divided its chromosomes into two new nuclei. The cytoskeleton of the cell is currently
pinching the cell in the middle to form two new cells.
In which stage of the cell cycle is this cell? - CORRECT ANSWER - Cytokinesis
What is the function of the histones during S phase? - CORRECT ANSWER - Organizing
and helping to unwind the DNA so the replication enzymes can access it
What is the function of the flagellum? - CORRECT ANSWER - Locomotion and sensing
What is true of a eukaryotic cell? - CORRECT ANSWER - It contains mitochondria.
Some cells need to maintain a set concentration of Na + and K + ions. These cells are able to do
this with the help of the Na/K pump, which transports these ions from areas of low concentration
to areas of high concentration (against their concentration gradient). Na + is pumped out, and K
+ is pumped in.
Which type of membrane transport is involved in this action? - CORRECT ANSWER -
Active transport
Choose the two substances that are the main components in most eukaryotic cell membranes. -
CORRECT ANSWER - Lipids and proteins
