Answer:
a. DNA replication proceeds in a 5' to 3' direction in the new DNA molecule and in the opposite direction in the original
c. Each new DNA molecule contains an original strand and a newly synthesized strand.
Explanation:
DNA replication is an important process every cell must undergo prior to division. DNA replication is the process whereby DNA content is doubled. It occurs as a result of an enzyme called DNA polymerase, which synthesizes nucleotides.
DNA replication follows the semi-conservative model which uses one original DNA strand to synthesize a new DNA strand. The double-stranded DNA is separated into two single strands which serve as template for new strands. Due to the action of DNA polymerase, DNA replication proceeds in a 5' to 3' direction in the new DNA molecule and in the opposite direction in the original.
Also, each newly synthesized DNA molecule which is similar to one another contains an original strand (template) and a newly synthesized strand.

Hydrolysis is equals to hydro which means water plus lysis which means splitting. Therefore, hydrolysis means splitting/breaking a chemical bond by the addition of water (H2O). More accurately, it is by the introduction of the elements that make up water which are hydrogen and oxygen. Simple example of hydrolysis reaction is an ester is hydrolyzed into an alcohol and a carboxylic acid. Condensation on the other hand is the opposite of hydrolysis. Condensation occurs when two Hydrogen and one Oxygen are LOST from a compound or compounds during the reaction. Most often this occurs when 2 reactants form one product were bond between them being formed by the concerted loss of water (H2O). Condensation example is an alcohol + a carboxylic acid -> ester + H2O.
