DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).

Answer:
B. False
Explanation:
Prior to the replication of a DNA strand or molecule, the double stranded DNA molecule needs to be unwound i.e. separated into two single strands. One strand called the LEADING STRAND that runs from the 3' - 5' direction while the other strand called the LAGGING STRAND runs from the 5' - 3' direction.
The unwinding of the DNA template is carried out by an enzyme called DNA HELICASE, which binds to the DNA molecule and unwinds the double strands into two strands at the same time. This means that the unwinding into leading or lagging strand is not easier than the other since it occurs simultaneously, hence, this question is FALSE.
