Viral replication




035 – Viral replication

Paul Andersen explains how viruses reproduce using the lytic cycle. It also shows how viruses can capture new genetic materials and how retroviruses (such as HIV) can enter the lytic cycle. It also describes the lysogenic cycle and how it increases the virulence of bacteria.

  1. Bozeman you are the shit?your videos are too good.

  2. HIV is a dna virus not rna…

  3. you are the best teacher on youtube. THANK YOU

  4. RNA viruses are not all retroviruses, for example rhinoviruses that you talked about in the beginning are RNA viruses but not retroviruses, as are influenza, parainfluenza. ebola and many more…

  5. Thank you so much for this video! This covered so much really quickly and you didn't pad it out with introductory information.

  6. That's only one category of viruses:( I need help with -sense and amibisense rna viruses like bunyavirus

  7. I know I am asking  damm Q but I am confusing here prof. do viruses infects bacteria or cell? what is the connection …. what is my point here  bacteria cell and Eucaryato cell can affect by viruses at the same time? thanks

  8. Awesome,​ concise information. Thank you very much.

  9. Clear and accurate explanation. Thank you!

  10. Mr. Anderson are there any new videos for this year 2017. I really understand your videos better. Thanks you are the best.!!!!!!!!

  11. So we need to maintain our body hydrated not to let the virus get off the lytic cycle until it's completely gone?

  12. THank you for helping me pass my final fam. I apreciate it

  13. So useful and clear !! Thanks so much!!

  14. thanks. it was a great explanation 🙂

  15. OMG the commercial prior to this is rediculous

  16. I got 99 problems but a Rhiniovirus ain't 1

  17. When you're watching this before your internal finals and NBME exams, in spanish #ayvisne

  18. But there is no explanation about replication of other RNA viruses. HIV has a specific replication, but you haven't talked about viruses with + sense RNA and – sense RNA.

  19. Can you create supplements (practice questions that are intricate) for AP Biology? You would save the lives of many students. Thus you will acheive being a biology teacher and a doctor. You're welcome 🙂

  20. You really made bio interesting

  21. One does not quote Benjamin Franklin in a normal, unedited voice.

  22. Just had to say that you have a very defined jawline.

  23. thank you sur… really helpful

  24. Thumbs up if you'r watching this before a bio test! Ugh…

  25. This was so helpful! Thank you for this 🙂

  26. Does an RNA virus use the enzyme in the host cell to become lysogenic?

  27. Cold sore's are cool. Nice Mr. Anderson

  28. Thanks so much, I finally understand!

  29. Ms. Ramsey's 2nd period.

    ayyyyyyyyyy

  30. Great clear explanation! Thanks!

  31. its Saturday, I'm 17 and party's are happening… what am i doing with my life.

  32. I got 99 rhinoviruses but the coronavirus ain't one
