Move aside Mendel! Life isn’t all peas and carrots and some rules are made to be broken. Episode 65 recaps several patterns of non-Mendelian inheritance including incomplete dominance (1:59), multiple alleles and codominance (3:21), sex linked recessive traits (5:41), recombinants (7:14) and polygenetic traits (8:14). Get ready to practice your Punnett squares!
The Question of the Day asks (9:39) What organism did Sir Thomas Hunt Morgan perform genetic experiments on while developing his chromosomal theory of inheritance?

If I flip a coin, what are the chances it will land on heads? Find out all about probability according to Mendel in Episode 64. Two of Mendel’s major observations are highly rooted in meiosis and the manner in which homologous chromosomes separate (2:08). Get some Chi-Square testing with some awesome brave corn (4:34). The rules of probability can be applied to study the passing of single-gene traits through generations (7:06).
The Question of the Day asks (8:23) What male plant structure produces pollen?

Even the closest siblings are genetically unique, thanks to a microscopic DNA dance known as meiosis. Episode 63 begins with a recap of chromosome structure and homologous pairs (1:48). In order to reduce the chromosomes number in half, the cells will need to go through PMAT twice. (2:53) When does meiosis occur and why are the haploid cells different? (7:19)
The Question of the Day asks (9:35) True or false? Mitochondria are inherited through egg and sperm.

What did the cell say when her sister stepped on her foot? MY TOE, SIS! Episode 62 recaps the process of nuclear division which creates two identical diploid cells. (1:12) Mitosis has four main sequential events - prophase (3:57), metaphase (4:31), anaphase (5:10) and telophase (5:36).
The Question of the Day asks (7:20) What protein filament creates the contractile ring in animal cell cytokinesis?

You have the ability to respond to stimuli on so many levels - molecular, cellular, physiological, and behavioral! (0:55) Maintaining internal conditions despite external and internal changes is the basis of homeostasis. There are two types of feedback mechanisms used by organisms - negative (2:30) and positive. (4:48) Homeostasis links to several units of study in the curriculum (5:37).
The Question of the Day asks (7:18) What paramecium organelle pumps out excess water when the cell is placed in a hypotonic environment?

The cell cycle consists of interphase, mitosis and cytokinesis.(1:33) There are a number of internal checkpoints that regulate a cell's progression through the cell cycle, including cyclins(4:23) and Cdk complexes(5:23). These couple with phosphorylation to activate target proteins throughout the cell cycle.
The Question of the Day asks (7:38) Some cells, like neurons, exit the cell cycle prior to the S phase - what phase are they in?

If you are ever lucky enough to have a major scientific discovery, you’d probably name it after yourself too. Melanie recaps each scientist's background (1:05) (4:26) before discussing the main events of the Calvin Cycle (1:40) and Krebs Cycle (5:02). The Calvin cycle forms sugars in the stroma of chloroplasts while the Krebs cycle oxidizes sugars in the matrix of mitochondria.
The Question of the Day asks (7:19) What group of biological molecules does the coenzyme NADH belong to?

Like Pacman, enzymes have specific shapes, act on smaller molecules and can be destroyed by external factors. Enzymes are made of proteins - each having a unique structure for a specific function.(1:10) Melanie explains lactose intolerance (3:30) before straightening her hair for a night out (5:43). There are several environmental factors which influence enzyme functioning (6:41). Disrupt those hydrogen bonds or R group interactions and lose structure as well as function.
The Question of the Day asks (9:38)Which amino acid corresponds to the start codon - AUG?

Electrons are going to enter a membranous pinball machine in episode 57. The electron transport chain is found in the process of photosynthesis (2:10) and the process of cellular respiration.(4:30) This recap will first focus on structure and function for each respective organelle before drawing similarities (7:34) and pointing out differences. The episode concludes with unit connections and exam tips! (8:29)
The Question of the Day asks (9:43) True or False?Sequentially, photosystem I precedes photosystem II in the thylakoid membrane ETC.

Let’s put our sneakers on and go for a run while listening to Episode 56! Melanie begins by debunking some myths to make our chemistry and physics colleagues happy (1:30). Next, remember key activation energy concepts (2:43). Lastly, analyze two graphs to distinguish between energy storing and energy releasing reactions (4:36).
The Question of the Day asks (8:02) True or False? ΔG is constant in catalyzed and uncatalyzed reactions.
