Recombination at
the Molecular Level III
The two DNA
molecules are now covalently linked in an "X"-like
cross configuration, called a heteroduplex.
As the chromosomes are pulled away from each other during
meiosis, each double-stranded structure unravels so that the
point of linkage "migrates" towards one end of the
molecule. [Imagine that the centromere
is to the left: pulling the A and a ends away
from each other causes the branch to move in the direction of
the B-locus markers].
