QUESTIONS WITH ACCURATE ANSWERS
A ___________________________ holds the sister chromatids
together. correct answer centromere
All prokaryotes and some eukaryotes reproduce this way. correct
answer Asexual reproduction.
At which phase of meiosis does crossing over occur? correct answer
Prophase I
Corresponding chromosomes from the mother and the father of the
organism undergoing meiosis are physically bound, and X-shaped
structures called ___________________ form. correct answer
chiasmata
Explain binary fission. correct answer A prokaryotic cell, such as a
bacterium, copies its DNA and splits in half.
Binary fission is simple because only one parent cell divides into two
daughter cells (or offspring) that are the same size.
, Explain cellular respiration. correct answer It is the process by which
the mitochondria of a cell breaks down glucose to produce energy in
the form of ATP.
Explain cytokinesis in animal cells. correct answer Animal cells split by
slowly pinching the membrane toward the center of the cell as the cell
divides.
The actin cytoskeleton performs the pinching-off operation.
Explain cytokinesis in plant cells. correct answer Plant cells build a new
wall, or cell plate, between the two cells.
Microtubules are more important for cytokinesis in plant cells.
Explain glycolysis. correct answer 1 molecule of glucose breaks down
into 2 smaller sugar molecules called pyruvate.
This is an anaerobic process and doesn't require oxygen.
It takes place in the cell's cytoplasm.
Explain meiosis. correct answer Sexual cell division in eukaryotes,
involving 2 phases of mitosis that take place one after the other but
without a second replication of DNA.
