Question 1
What typically initiates homologous DNA recombination?
◦ A site-specific nick in one strand of duplex DNA
◦ A site-specific double-strand break in duplex DNA
◦ Strand invasion with breaking the DNA
◦ A random nick in one strand of duplex DNA
◦ A random double-strand break in duplex DNA
Question 2
When chromosomes begin to separate during meiosis, they can be observed to be held together at discrete sites called:
◦ monovalents.
◦ bivalents.
◦ Holliday junctions.
◦ synaptonemal complexes.
◦ chiasmata.
