1. Sugar
A sugar and phosphate
make a nucleotide.
Adenine and Thymine
are always paired
together. Guanine and
Cytosine are always
paired together as
well.

19. The leading
strand
synthesizes from
a 3’ to 5’ end and
the lagging
strand
synthesizes
discontinuously
in a 5’ to 3’
direction. This
completes DNA
replication
