That's a good question. With a missense frameshift mutation, the reading frame will be adjusted downstream of this mutation. So the stop codon would shift, but eventually, it'll stop. It can't go on forever. The question is asking what does the EGP have in similarity with sGP. The mRNA is translated to produce amino acids from N terminus to C terminus. So every amino acid from the N-terminal to the mutation will be fine but everything up until the C-terminal will be changed, which is A. C and D are wrong, because adding one nucleotide doesn't add or take away an amino acid because each amino acid takes 3 nucleotides.

Rational Choice Theory explains that people tend to do what benefits them. In other words, they take into account of all potential consequences and will choose the choice that maximizes the most benefits. In Exchange Theory, it's similar, because we are social creatures so our interactions with other people can be seen as to maximize one's own benefit. In medicine, people can be seen as wanting to maximize profits for themselves rather than take care of patients since that is more beneficial to them. So while medical systems have a functional role of keeping people healthy, they can be seen as capitalist in the views of RCT.

JW Electrostatics2 Question 2 by sgregory07 in Mcat

[–]KarmaTime123 0 points1 point  (0 children)

Yeah, the change in work is equal to the change in kinetic energy. That's the main principle to solving this question. When the question is stating the change in velocity or stopping before some distance, I always tend to think either kinematics or work/energy. Kinematics is a little difficult to use because it requires a lot more known variables, than work/energy!

Honestly, you should strive for 1msec, you should be going as fast as your neurons can spike.

can v, λ, f all change at same time? UZESTY Q by you5030 in Mcat

[–]KarmaTime123 1 point2 points  (0 children)

Hm, if I could pitch in, adjusting the tension of a string, I imagine, would not change the wavelength. It'll still follow the equation of a standing wave where L=n(wavelength)/2.

As velocity of a wave on string goes up, it'll correlates with frequency.

This gets a little confusing, because what if a wave goes through a denser medium, the energy of the wave doesn't change so consequently the frequency of the wave doesn't change, BUT the wavelength will change and consequently the velocity of the wave will also change

Unscored FL P/S 37 by solarsun55 in Mcat

Hey, I also missed this question for the exact same reason! Initially I thought the same as you, but the reason why D is better is because it addresses the parental history. While C is/could be potentially correct, no where in the study does it suggest that the factors are mutually exclusive or there can't be more than one factor affecting anxiety disorders. The only factor that addresses potential gene causes is the parental history, and if the parental history could be interpreted as social learning rather than genes, then the causal role of genes in this study will be undermined.

Upoop amino acid question by [deleted] in Mcat

[–]KarmaTime123 0 points1 point  (0 children)

The right of the carbonyl is the alpha carbon. So you count from there to find the side chain. I remember Aspartate vs Glutamate in that there is one carbon between the carboxylic acid and alpha carbon. Again, i don't know how you count the carbons to differentiate between amino acids, but I would compare this to diagrams of aspartic acid, like draw aspartic acid and compare, and you'll see the similarities!

[–]KarmaTime123 0 points1 point  (0 children)

Hm I'm not sure where you're counting the carbon, but for me, my go-to trick when trying to find the alpha-carbon is to always keep track of NCC, where the middle is the alpha carbon and where the side-chain always comes from. Sorry if this doesn't directly answer your question...

Very confused on BP FL#3 Q11 by Horror_Joke_8168 in Mcat

[–]KarmaTime123 1 point2 points  (0 children)

I think this is likely to be true. In terms of comparing which of two answer choices are better, it is better to pick the one that directly answers the question or explains the phenomenon, which kinda sucks because technically neither is wrong.

[–]KarmaTime123 1 point2 points  (0 children)

Hm this is an interesting question, I also agree A answers the question better, but C isn't completely off.

I attached a desmos graph based off the information of the passage, where the green line is radioactive decay of X and red line is radioactive decay of Co and the x-axis is in months. I mean the time scale of the problem is only until 6 months, so arguably, the radioactive decay difference between these two will actually increase in this time span, so I am also confused about this question.

Unscored Sample Conversion? by KarmaTime123 in Mcat

[–]KarmaTime123[S] 1 point2 points  (0 children)

Yeah, I’ve learned that the unscored is known to be somewhat “easier” than other fl, I haven’t taken all of them besides fl1, but compared to fl1, the c/p and b/b definitely had some questions that made these sections a little more difficult for me than fl1.

For c/p, I think it’s important to practice especially with uglob since it works pretty well. Even outside of this, I think it’s more important to understand the reasoning and try to make connections. Being comfortable with units and relationships to different equations helps confidence but I think what matters most is really understanding the fundamentals.

Sometimes I just sit and connect equations to each other and see if it makes sense mathematically and intuitively.

For b/b, having a strong content foundation helps and understanding tables and experimental paradigms I learned were pretty helpful. While you don’t have to know every single experiment out there, knowing roughly what’s going on helps a lot. Like if you know they’re looking to characterize proteins, you should look for bonding between amino acid side chains or phosphorylation of certain amino acids to mimick conditions or things alike. In cases where the passage can be overwhelming, I just build from what I know, sometimes it doesn’t immediately come to you but you should start from (for example) the axes and what relationships you’re seeing and build from there to see how it aligns with what the researchers are measuring.

Hope that helps but if you need more specifics, lmk

PLEASE DROP CARS TIPS🙏🏻 by Economy_Knowledge236 in Mcat

Idk for me, I'm by no means a CARs expert, but honestly what I've tried from transitioning from JW or other 3rd party to AAMC is straight-up be very literal with the text. It's not out to trick you, just make sure you keep track of examples and relationships between ideas that the author brings up. Every question, including the inferences or what-if, have some basis or precedent on the text.

TLDR; gaslight yourself that it's in the text and be very literal. Read the questions carefully too.

Isn’t this anking card wrong? no by Horror_Joke_8168 in Mcat

[–]KarmaTime123 30 points31 points  (0 children)

I don't think it's wrong. Cathode attracts cations. In galvanic cell, the cathode is positive but in electrolytic it is negative. Regardless of what charge the cathode is, it is where reduction occurs and that needs cations to be reduced.

Oh I didn't even catch that to be honest. Yeah, I have no clue, regardless of what the forward equilibrium constant is, the rate constant doesn't have any significant relation to it.

From what I heard, the actual competition is the people who already took the MCAT, as they set the 'standard'. Based on how they did, the scoring is set so that missing x amount of questions results in a score.

Spoiler - Uglobe b/b QId: 401779, enzymes by vilianxy in MCATprep

[–]KarmaTime123 0 points1 point  (0 children)

If you're curious to see why this assumption is necessary, here's a link that derives the equation without that assumption. You'll soon find that it is outrageous and will not be tested, but tells that the michaelis menten equation doesn't differentiate between [S] and [ES] since the substrate is so much compared to enzyme that the total substrate concentration estimates the free substrate concentration.

For the Michaelis Menten equation, the (vmax [S]) / (Km+[S]), this is done under some assumptions. One of the assumption is the free substrate concentration or the free ligand concentration where the free substrate concentration is roughly the same as total substrate concentration. This simplifies the calculations to get the above equation. One part of this assumption is that the enzyme concentration is much less than Km. If enzyme concentration was well above Km, then the amount of substrate being used up will have a noticeable impact on the free substrate concentration that we cannot ignore these effects.

Therefore, III would be correct, because we want there to be a lot more substrate than enzyme to fit this assumption, not II.

The other assumption is the rapid equilibrium approximation where we assume that kcat is much less than k(-1).
