DNA and RNA Viruses Mnemonic for USMLE Step 1

mnemonic to memorize all viruses and their structural components (DNA RNA capsid envelope circular etc) in 13 minutes

[@lhidalgo8363]

I had 1 million neurons to learn all this content and thanks to you, now I will only use about 100...great job!!

[@michaelfunaro9150]

not for nothing but the 4 people who disliked this video are fried as fuck

[@grayscalegoddess]

Literally had tears in my eyes while watching. This helped a whole lot! THANK YOU!!!

[@WJFP32]

Not that these are any better but for DNA Naked I think "Dana (DNA) and PAPP aka Dad/Granddad (Parvo, adenosine, papilloma, polyoma) are naked". For (Neg) RNA to help remember "Bad Prof (professors) get a (Neg) Rating (RNA)". Cheers if it helps someone.

[@ameeraradjuli2538]

Wow this is so helpful thank you so much for sharing!! I’m having a hard time studying viruses for they sound alike

Thanks Matt really helpful

[@kaladkarinMD]

Thank you! This has been so helpful

[@RR-zl5kg]

Is Parvo + or -, he said negative ssDNA, but schools says postive, and google says both. I know Group 2 so going with +, but would love confirmation.

[@havvanurozekici]

This is so good, helped me very much. Thanks :)

[@TheOpenRoadExperience]

hi what do you mean of circular DNA in BAD mnemonic? is it supposed to be RNA? thanks! nice vid btw

[@ASHISHSINGH-ld9do]

CIRCULAR GENOME

[@zumpzumm]

Watched it over a year ago for micro, drew it about 10 times and still remember the salient points. Watching again to refresh for step1 studying. Every bit of important structural virology in 10 minutes! So awesome thanks dude.

[@Nomolivin]

How did you prepare for step 1? Could you please give me some tips

[@angelicapadua]

I love this! ❤

Matt Skovgard can't really thank you, salute to your effort👍👍

[@RameshKumar-dr7zl]

Wonderfulllll video..Helped me a lot.. Thank you 😊

[@emaan6740]

Draw little mountains next to Reovirus which will remind you of Rotavirus causing villous atrophy (villi look like mountains) and Coltivirus causing Colorado tick fever (mountains in Colorado).

[@zeppage4]

For polyoma, I keep thinking Jesus Christ loves Burger King. Maybe it'll help someone remember too. :) Great vid!

what did you say the BAD PROF group's theme was? "Grab Bag" viruses?

[@williamclements310]

HE'S LEFT HANDED DON'T TRUST HIM!!!!!!!!!!!

[@foolzor123]

Amazing for micro shelf. had at least 10 questions that were straight up based on knowing whats ss/ds/rna/dna. see how step 1 goes in a month.

[@sasohal]

+foolzor123 how was the step (how are clinicals too?)

[@leebaumgarten]

Awesome! Great job, just one thing about the hypermutation part with the BOAR. Do you mean segmentation is important for reassortment and can cause epidemics, instead of hypermutation?

[@mattskovgard749]

Hey Lee, Oops, yes that's exactly what I meant. Segmentation is key for reassortment of the fragments, not for hypermutation, and this reassortment can lead to epidemics, NOT endemics. Thanks for praise!

[@gregmcwhir7313]

Matt Skovgard I would lean more toward pandemic because the reassortment is often causing genetic shift. Epidemic for hypermutation?

[@xSmithx]

@@gregmcwhir7313 studying for step 1 rn. came across this on Amboss: Segmental viral reassortment has the potential to cause antigenic shift and increase the Reovirus's PANDEMIC potential.

[@mypuppyarnold91]

[@princesszsay]

you're a doctor now, huh

[@shahjahan3413]

I'm doing it for my MDCAT 🤡... Will think about USMLE later

[@10FMatuszak]

Thank you! I'm just gonna draw this out everyday for the next week or so and hope it percolates into my brain.

[@bryancstephens]

+Frank Matuszak It will.

High five for being a leftie and taping it. Right handed people will never understand the struggle! Wonderful mnemonic and extremely helpful.

[@mattskovgard749]

Haha how astute of you. #leftiesunite

[@UrsantaHoHoHo]

@@mattskovgard749 lefties are geniuses

Or you can write like Leonardo da Vinci in mirror fonts from right to left so no-one can read it.

[@haubui5481]

This is AMAZING! Thank you very much. Good luck on STEP 1 everyone.

[@lilypeasize]

great! thanks. I would add somewhere (as I just got a ? on this) that all the DNA viruses that are enveloped get their envelope from the nuclear membrane - except for Herpesviruses - they get their envelope from the plasma membrane!

[@mattskovgard749]

Thanks lilypeasize! You're right, herpesviridae all get their envelope from the cytoplasmic membrane. Poxviridae are also a little weird. They replicate in the cytoplasm and get their envelope (actually 3 envelopes) from endosomes, ER, and the Golgi. They then exit the cell with no cytoplasmic membrane or nuclear membrane component. They exit by fusion with the cytoplasmic membrane (losing one envelope resulting in 2 envelopes when they exit). I think Hepadnaviridae translocate to the ER before they bud, so they actually receive their envelope from the ER. I'm not so sure about this one though. Needless to say, all this sounded way to complicated for my video. I'm not sure which viruses definitively receive their envelope from the nucleus. It maay be something Kaplan made up, but I'm not sure. What question did you do? What did it say?

[@lilypeasize]

It was on UWORLD Q bank (Step 1...). It specifically asked which viruses get their membrane not from the nuclear membrane... very specific question! I didn't know it yet, but it is in First Aid.

[@ayushsutaria]

Wait I'm looking at first aid now and it says the opposite. It says that herpes gets its envelope from the nuclear membrane....

[@mmertaban]

Ayush Sutaria You're righ Ayush. I think lilypeasize meant the opposite. All DNA viruses get their envelope from the plasma membrane, except for Herpsevirus -- it gets its envelope from the nuclear membrane.

[@kimberlypuddicombe2707]

Ayush Sutaria so what happens in this case

[@myspringatgate2007]

The only thing I "dislike" about this mnemonic is that i am just now discovering it as a second year! This would've made my first year so much easier... Oh well, better late than never. :) THANK YOU and best of luck with your future endeavors.

[@atlantic7949]

Isn't the corona virus helical?

[@mehaknarang5157]

Great video! thanks PS who else thought of calici as 'THE KHALEESI" :D ? haha

[@team6021]

Only ur GOT obsessed brain lol

[@prajjwalkunwar9287]

I studied from this video before my step 1 and i have sent this video to many of my fiends and juniors. Cant believe it was made 8 years back. Thank you so much for sharing your mneumonics its such a hard topic.

[@mattskovgard749]

Thanks! Glad it served well

[@lovelylibra7349]

memoried in 2 days thank you so much! this boosted my confidence

[@taufiqzaidi1929]

i think u missed astrovirus

[@smoothsoulbrotha]

This video should have way more views. Definitely a lifesaver. Thank you!

[@khateebyassin]

great, thank you, I think you missed Chikungunya Virus, anyhow that's the best show from all the other youtubers

[@latashastabler7588]

This video was golden for step 1. Now I'm refreshing for the peds rotation. Rubella isn't technically a toga anymore, but still soooo helpful! Thanks!

[@annamathew2449]

Hi, you said DNA is always positive sense because it is double stranded? I thought that virus could either have double or single DNA strands?

[@fire0305]

This is really helpful! 1 quick note is that HIV has a conical capsid, not an icosohedral one (HTLV does have an icosohedral capsid). Otherwise, this is great!

[@dr.petersonlorins2415]

You're awesome... I have come up with my own ways, but I must say that yours is more impressive LOL

[@ASHISHSINGH-ld9do]

YOU DESERVE NOBLE PRIZE FOR THIS !!!

[@dinorahjaime3317]

great mneumonic but man gotta laugh at the unconcious bias with flava flave vs rubella lol. flava flave is washed up but rubella is beautiful?? haha

yep!

[@nicksullivan9423]

this is phenomenal. ive showed all my buddies in med school and it has made our lives much easier

[@ameeraradjuli2538]

Hi!!! I’m actually looking for the way how to study smart with the viruses and (it’s a lot to remember and they look and sound a like so it’s kinda hard to remember for me without a concept map in which I always do but this time it’s already 1 am and I don’t wanna go to sleep without familiarizing viruses.) Thank you so much this is really a big help for me even though it’s 6 years ago, very useful for a student like me who study on their own.

[@kierankettyls2290]

isnt coronavirus helical, and positive sense?

[@HashemSmashem]

+Kieran Kettyls he mentioned that at minute 12:30

[@cheena97]

this was a great help! you should do more. ty

[@CPapenfuss22]

GOAT! This helped tremendously in medical school. Thanks

[@tasniaaaaaaa7667]

I’ve been watching this video to review this for 2 years now, but just here to say this video is one of the best things that happened to me in med school

[@ada3360]

6:18...... i think no one will forget this one.

Isn't the lyssavirus in the Rhabdoviridae family? Considering it is the cause of rabies?

[@paulawad9585]

thank u so much bro u really saved my life i always know the virus the Q is talking about but i i could never get the answer right because it would ask me about the characteristics of the virus on the MCQ... i no longer have this problem thanks to u :) God bless u brother

Reo is negative sense though

[@ninaqueena1]

Hi there! Thank you so much for this amazing video!I was wondering if you or anyone else could possibly explain what you mean by DNA viruses being + and - ? I thought that being positive of negative sense was something that involved RNA viruses only. I've been looking everywhere on line with no avail. Thank you once again

[@altair2038]

did you find out? need to know too lol ( i think after 6 years you might have figured it out HaHa )
