The idea is to strike a balance between sufficient detail while staying as concise and HY as possible for USMLE (i.e., I’m aware some students want me to just cut to the chase with HY factoids; others want more in depth discussion of every mechanism). I will also make a separate doc specifically addressing more of the pedantic genetics stuff. Relax. - Student question showed DNA being replicated and they pointed to enzyme at replication fork; what’s the enzyme? à answer = helicase. - Question asks what is acted upon by DNA ligase to form a DNA sequence that aligns complimentary with the leading strand in DNA synthesis? à answer = Okazaki fragments; the lagging strand in DNA synthesis is composed of Okazaki fragments that are synthesized discontinuously and then amalgamated using DNA ligase.
