Bio Beyond - Cellular Replication Questions
with Correct Answers
You might think of how parents look like their children. Their shared characterisitecs
are coded in the DNA passed down by the parent. This DNA is in all cells, which copies
itself as one cells divides into two. Do you think this process is the same for all cells?
No, because prokaryotic cells would need more complex processes due to the cell wall
Prokaryotes, being smaller and less complex than eukaryotes, replicate using a simple
process called binary fission. Listed below are a few steps which must happen during
the process and a few that don't.
See if you can identify which steps should occur in binary fission below:
DNA is copied in place
Cell wall and membrane pinch closed
DNA migrates to either side of cell
Two genetically identical cells are present
You now know the steps of binary fission in prokaryotes. See if you can order the images
from the first to last step starting on the left.
Binary fission is used by:
Prokaryotes
And produces:
, Two genetically identical cells
Eukaryotes (plants, animals, and fungi) reproduce differently than prokaryotes on a
cellular level. Which of the following do you think contributes most to this different
process?
Eukaryotes generally have larger genomes
Normally, the cell is in a state called interphase, which has three stages - G1, S, and G2,
shown to the right. In interphase, the cell is performing its normal functions, but toward
the end some changes begin happening. What do you see happening in the images to the
right?
The genetic material is being copied
REPLICATION
Interphase (G1/S/G2) - Prophase - Metaphase - Anaphase - Telophase - Cytokinesis
The first stage of mitosis is called prophase. The images to the right show a cell both
before and after prophase. What appears different?
The genetic material has condensed
Shown on the right is an enlarged version of the diagram of the cell after prophase, in
which X-shaped structures called chromosomes have condensed from chromatin. Do
you think chromosomes would always be shaped like an X? Why or why not?
No - other organisms might have differently shaped chromosomes
Shown at right is a diagram of a cell in the second phase of mitosis, metaphase. What
has happened in metaphase? Select all that apply:
