Life on Earth 003 - Viruses
Paul Andersen describes the important characteristics of viruses. He starts with a brief description of origin theories. He then describes the two characteristics of all viruses; genetic information and protein coats. He also describes how some viruses use specialized envelopes to gain entry to their host cells. He also explains the lytic and lysogenic reproductive cycles.

i sometimes watch khan academy and crash course videos BUT mr anderson's are my fav

@janezhang4114 8 лет назад

+Blue k I agree, crash course is too vague but Khan academy is too detailed

@pink1440 9 лет назад

Bozeman science is literally what is saving me in AP bio right now and it really deserves more credit. I also use Crash course and I love the Vlogbrothers but while they make things more visually appealing, their content isn't as helpful. Thanks Mr. Anderson.

I've watched a lot of Mr. Andersen's videos, and I say with confidence that "shingles" @ 7:37 is his greatest moment. Thank you for your plethora of helpful videos!

@mikemills4672 9 лет назад

Kids now a day don't realize how good they have it. Mr. Anderson's videos are unbelievably helpful to high school and college students alike. I wish there were videos like this when I was a student many years ago. This is another great video by Mr. Anderson.

@arvinakbargumilang2000 9 лет назад

This channel is very underrated. Got only 10% than other popular youtube lesson channel. Yet,this channel has the most detailed,complete content, than any other. And btw im a highschool student on the last year. And i reallly lazy on reading. This lesson is unbelievably helpful Thanks to that guy on the video!!

@Big_ric 6 лет назад

arvin akbar gumilang yea these videos are awesome. Been watching yesterday too for a test today. When i saw that chapters 16-19 were like 100 pages and I hadn’t listened in class because my teacher sucks and everyone else is sleeping, there’s like 2 people taking notes, I was just like yup it’s RU-vid time. Read about 6 pages in on my book and picked up like 2 things. This channel explains stuff really well and has great visuals which is just how I learn.

@thewolfes146 4 года назад

Yes, this is definitely the best science lesson channel. The other ones are too foucsed on animation and making stupid jokes.

@AS-zm6vm 8 лет назад

I can't begin to explain how much your videos help students that are struggling with certain topics. God bless you.

I am a zoology student, and there is so much competition these days to get into a good college. You give a very basic and quality information about biology. You are helping so many students all over the world. THANK YOU. and your teaching style is very good. p.s I love your voice!! :)

@pitfulll6859 2 года назад

Hey! This is quite a while since your initial comment so I don't know if you'll respond, but how did college go for you :D?

@MelissazYla 11 лет назад

do you have any videos on biosynthesis of RNA viruses. I am having issues understanding the differences between sense strands and antisense strands

@Primalxbeast 11 лет назад

I also had a college biology class in which everybody was given the project of argueing against each other online, either for or against including viruses as life forms. It was a long time ago, but I'm pretty sure I picked the argueing for including them since not counting them wouldn't have been much of a challenge to argue for since those arguements have already been made.

@TheDaimon888 7 лет назад

Hi Paul great video as always I like your videos their very informative and educational, I was wondering if you would consider doing a video on Giant DNA Viruses let me know your answer thanks, happy New Year!

@Primalxbeast 11 лет назад

@Kristof630 That was ment as more of a thought experiment than as something to be taken litterally. As someone who likes sci-fi I wonder if we might end up broadening our definition of life if we knew more of what sort of things exist in the universe, and not just this one planet.

Hi, so I have question about viruses. Do viruses need energy for certain things, if yes where do they get this energy from and why can't they generate their own energy? I'm looking forward to hearing from you , Kind Regards, Senna

@KristofWakoli 11 лет назад

I think saying that we're not alive based on how we need energy from plants is an over generalization of what was said. Sure, we depend on other things to keep us alive but our cells make and reproduce without the need to attach to anything else for assistant and can live on their own, basically.

@SrmthfgRockLee 11 лет назад

yeah.. I gotta study biology here as well(kinezitherapy or rehabilitation).. gna be hard

@Primalxbeast 12 лет назад

@StevoKHS But first, the plants have to make those macromolecules, just like humans had to make the computers. I'm not claiming that viruses are alive, I'm just saying that the arguement that they can't proform basic functions and exist without the help of other organisms could also be considered true for any organism that has to get it's energy from other organisms.

what are bacteraphages bad?

@eblair6636 7 лет назад

DarkDestiny3 some aren't. It depends on what kind of bacteria it attacks. In new medical methods bacteriophages are used as an antibiotic to cure certain sicknesses.
