Which of the following is true of DNA Replication?

• DNA is semi conservative because it creates two new strands of old nucleotide.

• New DNA strands are being synthesized in the 5' to 3' direction

• DNA is being synthesized in the 3' to 5' directions from a template strand

• RNA is being synthesized by RNA polymerase in the 5' to 3' direction

• A sense strand is created from a nonsense strand of DNA using RNA polymerase

Which of the following is true pertaining to deoxycytidine monophosphate being added to a growing strand of DNA?

• It is a nitrogenous base found on prokaryotic chromosomes

• When translation of mRNA occurs, it reads in the 5' to 3' direction

• The phosphate group of dCMP will bond with the oxygen atom of a growing DNA strand

• Cytosine and guanine would not bond properly if the strand grew from 3' to 5'

• A phosphodiester bond is formed between the sugar and nitrogenous base of parallel nucleotides.
