Only two FRQs? - Piece of cake! Episode 24 discusses the FRQs on the 2020 exam (1:05) with a few tips and tricks. Practice makes comfort! Set up your exam space now and practice with a timer (2:44). Complete those practice questions in two different colors, to reflect on your timed answers (3:20). Learn how to translate the questions out of AP language and into “I’m sitting at home with my dog” language (4:05). Don’t have science vomit with your words! (4:40). Scrap paper may also be useful.
The Question of the Day asks (5:41) “Which Science Practice skill will not be represented on the 2020 exam?”

Deep breath! Episode 22 answers all of your questions about the updated exam structure. When is the exam going to be? (1:12) What is the exam going to cover?(1:46) How is the exam going to be structured? (2:20) What device should I use? (3:22) What about test security? (4:30) Will scoring be different? (5:11). Give it your best!
The Question of the Day asks (5:50) “What type of calculator will you need for the exam?”

Operons! Get your operons here! Episode 21 explains how the same DNA instructions can indicate Gene regulation begins with chromatin structure (1:40). DNA has areas of regulatory sequences which control transcription (2:30). Don’t get lost in the promotor, regulator, activator lingo - but focus on the effect of molecules interacting with the DNA strand (4:00). Regulation can also occur through alternative splicing of an mRNA transcript (4:30). Melanie concludes by recapping the learning objectives from the CED (5:05)
The Question of the Day asks (6:48) “What is the effect of a nucleotide insertion or deletion?”

Episode 20 dives into all things transcription and translation with the Central Dogma! Don’t forget that you are what your proteins produce. The mRNA transcript is named after the Latin word for writing (1:50). RNA Polymerase will synthesize mRNA in the 5’-3’ direction, just like DNA polymerase. Do you know Chargaff’s rules? (3:22). The mRNA transcript will need to go through modification as it exits the nuclear pore (3:40). Translation involves mRNA, rRNA and tRNA to form the polypeptide (4:50). Almost all organisms use the same genetic code which supports common ancestry (6:00).
The Question of the Day asks (6:48) “Which enzyme copies the viral RNA genome into DNA for the assembly of new viral progeny?”

Melanie recAPs DNA Replication by reviewing the role of enzymes. DNA Replication is semiconservative and occurs during the S phase of the cell cycle in eukaryotic cells (1:20). How does the structure of DNA influence the process of replication? (1:40) The CED requires you to know the function of the following enzymes: topoisomerase (2:38), helicase (2:48), DNA polymerase (3:25), and ligase (4:35). There are distinctions between replication patterns in prokaryotes and eukaryotes (5:00).
The Question of the Day asks (5:39) “What is the condensed, identical DNA strand called during mitosis?”

Episode 18 recAPs all things Mendelian and Non-Mendelian in the genetics world. It's important to remember the Law of Independent Assortment and Law of Segregation when reviewing pea experiments (1:30). Do you know what Pater and Filius mean in Latin? (2:00) The classic monohybrid flower example is broken down with a Punnett square walk through and vocabulary reminders (2:30). Always go back and reread the genetics problem when you think you’ve solved it! (4:00) Melanie concludes the episode by providing heredity examples of Non-Mendelian genetics (5:00). Don’t forget that mitochondria and chloroplasts have their own genes! (5:55)
The Question of the Day asks (6:40) “Explain how sexual reproduction increases genetic variation.”

Melanie recaps DNA in all its coiled and condensed forms during Episode 17. Beginning on the most microscopic level, (1:27) Melanie reviews the nucleotide monomer structure. You can create an antiparallel model with your own arms (2:45). Do you prefer a history or chemistry themed memory hack for nitrogenous bases? (3:40). DNA wraps around histones to form chromatin before condensing into chromosomes. The episode concludes with a contrast between prokaryotic and eukaryotic chromosome structure. (6:22)
The Question of the Day asks (6:19) “Which nitrogenous base is unique to RNA?”

Episode 16 gets some swanky tunes for sex cell and fertilization discussions (1:00). PMAT is coming back into play with new terminology of haploid and homologous pairs. Melanie begins with a recAP of Meiosis (2:39) before contrasting the two cellular division pathways(4:33). There are two main contributors to genetic variation through meiotic pathways (3:14). Melanie recommends organizing this information in a table when studying!
The Question of the Day asks (5:30) “When do human egg cells complete Meiosis II?”
