The 5' end of the nucleotide is the phosphate group (something to do with the arrangement of carbons), the 3' end of the nucleotide is on the other side where the hydorxyl group is (in other words, nucleotides link up via a phosphate joining a hydroxyl of another nucleotide in the chain). Don't worry, that stumped me for years, until half way through my first year of a medical degree actually!

where does replication in the lagging strand impose a problem? and what do they mean by replication 5' 3' . Arbitrarily, if 5 is representative of a point A, and 3 of a point B, does replication in the 5-3' direction mean replication from A to B? And how do we know which end is 5 or 3' and similarly which is the lagging or leading strand. thanks all

Generally correct, the video forgets to mention that the leading strand also uses RNA as its initial primer.
