Disc 5 of 6. Lecture 30 of 36. These molecular biology lectures are more concept-oriented than the detailed biochemistry lectures. #29, for example, in one lecture, covered cell division through mitosis and meiosis, recombination and swapping in eukaryotic reproduction, homologous end joining, homology-directed repair, antibody creation, gene activation and deletion, substitution, and CRISPR.

Lecture 26 "DNA Replication in Bacteria; PCR in the Lab" These lectures are from 2019 - but polymerase chain reaction (PCR) has become a household word in this era of COVID testing.

Disc 4 of 6. Lecture 24 of 36. This lecture is a hodgepodge of additional biochemistry topics. At the 2/3 point, the series will now transition from biochemistry to molecular biology.

Disc 3, Lecture 18, "How Plants Make Carbs And Other Metabolites" I needed to go over the section on the Calvin Cycle several times because of illegible graphic used to illustrate reduction, resynthesis of Ru5BP, and carbon fixation phases.

Disc 3, Lecture 16, "Cholesterol, Membranes, Lipoproteins", 28 steps to synthesize cholesterol, and Dr. Ahern makes a song out of it, to the tune of The Ants Go Marching. You gotta love a geek.

Disc 3, Lecture 13, "Metabolism Meets at the Citric Acid Cycle", Nicely done, to present the cycle forwards, and then re-exercise the catalyzing mechanisms in reverse, from alpha-ketoglutarate back to citrate and out of the mitochondria into the cytoplasm, as takes place in cancer cells.

Disc 2, Lecture 9, "Fatty Acids, Fats, and Other Lipids", Just a long list of chemical names, molecular structures, and biological functions. Sheer memorization; no concepts.

Disc 1, Lecture 6, "Hemoglobin Function Follows Structure", Wow, fetal hemoglobin protein function on the chemical level is amazing!
