300

What enzyme is essential for joining the Okazaki fragments?

Ligase 

300

what stabilized the single-stranded DNA after it is unwound?

ssBPs (single stranded binding proteins)

300

which type of bond joins the deoxyribose to the nitrogenous base?

glycosidic

300

which organism was used in the meselson and stahl experiment?

bacteria (E. coli)

400
What are the bonds that holds the backbone together?
Covalent bonds between sugar phosphates. Nitrogenous Bases are held together by hydrogen bonds.
