A concise review of the Khan Academy MCAT Videos. Ok this is really random but I just hit a thousand plays or this, so could you hmu with any critique? Email mcatstudyone@gmail.com (takes 20 seconds!) Created by Hamza Taj

  1. 15.08.2020

    8:3. DNA Libraries and Generating cDNA

    Prot —> mRNA —> cDNA —> dsDNA. (Step 2 via reverse transcriptase and step 3 via DNA Polymerase). Now the dsDNA is injected into a virus which infects bacteria to make lots of the DNA.

    5 Min.

  2. 15.08.2020

    8:2. Polymerase Chain Reaction

    Denaturation (Heat to high temp), Primer Annealing (Cool slightly), Primer Extension via polymerase (Heat but not as much as step 1).

    7 Min.

  3. 15.08.2020

    8:1. Gel Electrophoresis

    GE find us the length of a DNA Strand (how many base pairs long).

    7 Min.

  4. 10.08.2020

    7:5. Applying the HP Equation

    Not really sure why I did a module on this - basically you know they’re homo recessive because they have blue eyes (the recessive trait), and you know to use q BECAUSE we’re dealing with the recessive trait.

    2 Min.

  5. 10.08.2020

    7:4. The Hardy-Weinberg Equation

    HP Equation gives P(allele frequencies). P^2 is probability of homo dominant, Q^2 is probability of homo recessive, 2pq is probability of heterozygous allele combo. P = frequency of dom allele, Q = frequency of recessive allele.

    3 Min.

  6. 10.08.2020

    7:3. Worked Example: Punnett Squares

    Discusses Dihybrid Crosses and the Law of Independent Assortment.

    6 Min.

  7. 10.08.2020

    7:2. Co-dominance and Incomplete Dominance

    Don’t let the title fool you. This is short. Discusses complete, incomplete, and co-dominance.

    1 Min.

  8. 10.08.2020

    7:1. An Introduction to Mendelian Genetics

    Discuss genes, alleles, geno/phenotypes, and punnet squares. The Khan Academy video discusses the history (Gregor Mendel) but let’s be real, who cares.

    7 Min.
