Respond to each sentance with true or false regarding the replication of DNA:

Complementary base pairing relies on the number of hydrogen bonds that each base can make.

In a single nucleotide, the phosphate group is attached to the 5' carbon of the sugar unit.

The antiparallel arrangement of double-stranded DNA is due to the phosphate group being bonded to the 3' carbon on one strand and the 5' carbon on the complementary strand.

The phosphate attached to the 5' carbon of a given nucleotide links to the 3' -OH of the adjacent nucleotide.

The -OH group on the 3' carbon of the sugar unit is the attachment site for the nitrogenous base.
