Organization of DNA

[go to this section in the Guide]
Chapter Five: Cell Reproduction


Question 1
 When a cell divides, it doesn't just cut it's DNA in half because doing so would
   1.  give each daughter cell only half of the entire genetic "code"
2.  prevent the DNA from producing any proteins at all
3.  cause the organelles to be divided unequally
4.  cells do actually cut their DNA in half
 

Question 2
 DNA in prokaryotes is organized as a
   1.  circular shape
2.  dense mass called chromatin
3.  long, curvy line
4.  coil around proteins called histones
 

Question 3
 Before a eukaryote reproduces, it's DNA condenses into structures called
   1.  chromatin
2.  sister chromatids
3.  histones
4.  RNA
