AP Biology CED 6.2 - DNA Replication NOTE: The specific type of RNA polymerase that constructs the RNA primer during DNA replication is called "primase." This is beyond the scope of the AP curriculum, so I chose to simply call it an RNA polymerase (which IS in the scope of the curriculum- 6.3 Transcription).
Nucleic Acids AP Bio

NOTE: This video covers AP Biology content related to nucleic acids from Unit 1 (1.6- nucleic acids) AND Unit 6 (DNA and RNA structure). If you're in Unit 1- it's a good idea to get learn ahead!

I have a test tomorrow I have to study!!!
Science teacher sent me here, thank you Ms R! 😂
Good video
Best video u saw on the bases of exponential and logistic population growth ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤thanks love from jimcale
This video is extremely helpful......... THANK YOU ALOT!!!!!
who here for school
god bless you
Hi
My sci teacher sent me here
My teacher is using it (edit I don’t use it anymore)
Cheer~~~a bacterium, virus, or other microorganism that can cause disease.😊
Well-explained
I love this video and its so easy to understand thank you so much
Ay dude I watched this video when it first came out but came back to thank you because a few months ago I did a science test for my school and this was one of the questions I was subbed in when walking past so I thank you

GREAT JOB...THANK YOU!!! I am using this in all 4 of my high school classes I teach.
Bruh I’m in middle school and I need this lol
i’m cooked

Charles Darwin The Origin of Species is a Great Science Book 📕
It is a bit dated now but he did have a way with words.
Thanxxxx alot u made it clever more than anyone elsee🥹♥️♥️♥️♥️ Thank you !🥹🩷
Thank you
Wowww thank you!!! Now i understand!!!
thank you .
Anyone in 2024 over here? Add like if you’re here!
The "Debate" is over. Biological Evolution is science and has been accepted science for 150 years. Creationism is fraud, it is magic that has never been demonstrated and it has NO place in any science classroom.
That's what Fred Hoyle said about the Big Bang - he called it 'religious pseudoscience' and 'it's an irrational process, and can't be described in scientific terms' 'the debate is over' is an anathema to the scientific method.
@@SteveLomas-k6k All relevant evidence in astronomy points to the Big Bang so Fred Hoyle was wrong, just as you and your fellow creationists are wrong about Evolution.
thank you so much for this video!
Was it useful for the students to answers these questions
Make an example whereby you calculate the number of years it would take for maybe deers to reach a given capacity
Very clear explanation. Thank you!
Thank you
Very good slidehsow !!Good explanation 😂😂😂❤❤❤
You explained that so well! thank you
❤❤
the explanation is amazing. thank you for your video. it is easily understood.
Random mutation doesn't exist , it's called adaptive mutation or directed mutations , if evolution is true why bacteria don't change their type at all , bacteria e coli remain e coli even after mutation happen and it can no more what's written perviously in dna
Exam time🥲🥲
🤨That is neither proof nor evidence for evolution
I am not impressed by either ignorance nor arrogance.
Birds ARE reptiles though, unless crocodilians are not. Because crocodilians are more closely related to birds than to lizards or turtles.
“Science is a growing collection of knowledge” “YEAH THAT WE DONT NEED” I have a final exam and I have to studyyyy 😭😭😭😭😭
You’re kidding, right?
Dps 6 class hi
Best video on ecological pyramid.. thank you Rachel❤️
FUCK FUCK FUCK
The peppered moth experiment was later found to be a hoax. They glued the moths to the trees for their pictures.
Those pictures were staged, but the moths are real. They were *pinned to the tree to demonstrate the difference in colour and the effectiveness of the camouflage. Books/other publications that included this picture often failed to disclose the fact that it was staged, which led to the belief that it was some big cover-up. Also, because it is such a commonly cited example, it is often over-simplified, and evolution is anything but simple. These are the reasons behind the still-present controversy surrounding this discovery. The validity of the discovery itself is undeniable. The methods of the study have been validated, and the results have been replicated. I'm very happy to discuss this further if you're interested, but not to argue or "debate". Either way, I'm curious to know where you heard this, and hope you're having a good day.
Hey Teach! Great work on the chanel!!! I suggest you make You Tube SHORTS :) !!!! This will help your channel so much, just keep them short and interesting, basically what you do!! :)
Oops.
❤❤❤❤❤❤❤
this is how we learn. cool
Well, the Fossil record doesn't exist for evolution and claims on such things as the Piltdown man, Nebraska Man, Lucy and others have been shown to be either frauds or wild conjectures based on very few bones. The Comparative Embryology by Haeckel was a known fraud right from the beginning; from taking embryos from different developmental stages to changing the drawings to try and emphasize similarities that weren't there to claims on body parts that had nothing in common with different species while in development. Homology is not an indication of evolution. It's just a design that is efficient. As for DNA, the claim of apes and humans being 99.5% the same has now dropped to something like 80% because the methodology used was a pick and match system from different areas of the DNA. Even Chinese scientists are rejecting this tree of Life scenario from Darwinian Evolution and describing life as a forest. While Evolutionist want to claim that this theory is real, there is less and less evidence supporting it. From the problems inherent in Origin of Life chemical issues to the fact that no one has actually found any fossils supporting it. It's time to go back to the drawing board as this theory requires more blind faith than anything else.
@@PhilipK-xk4by There are no examples of a full skeleton found together for any of the so called ape to man progression. They are just parts that have more missing bones than actual finds. The rest is fantasy. Drawing hair, eyes, skin tone from bones is nonsense. Even using the chimp argument, the DNA is vastly different. Science keeps changing its claims as often as the Kardashians change men. The vast amount of DNA used to be called Junk DNA and now apparently it is incredibly important. You want mock the Chinese for actually having the intelligence to question evolution where in North America it's so much of a cult that even questioning it gets people fired, then fine, go ahead. At least they are looking at the problem. And a good Designer understands how to use designs over and over in much different situations instead of redesigning the wheel all the time. So that claim is again nonsense. And saying Homology IS evidence of evolution is nonsense claim. Oranges and apples are round, rocks are round. They are homologous in shape. They sure the heck aren't indications of evolutionary progress from rock to apple. People see stuff all the time and most of it is in their mind, not in the actual item. And Evolution is a theory. Micro Evolution can studied, but that's just variation within a species and it in no way represents the Macro Evolution that people try to claim is the same. They are not. And no one has seen Macro Evolution occur. As for the raptors, it's a supposition about the feathers, just like everything else in this Evolutionary nonsense.
You drank all the creatard koolaid didn't you? We know you did. You spew out all the old creatard lies as if they would impress us. Saddly for you, we KNOW your examples are all bullshit, lies, missrepresented and just simply wrong. Your assertions have no basis in reality.
@@walkergarya Insults are the most graceless form of conceding defeat.
@@SteveLomas-k6k When the OP is repeating lies that have been refuted for decades, calling them out as a liar does NOT concede defeat. I call out liars as liars. I see no need to respect liars and frauds. If you do not like that, do not lie to me and it will not be an issue.
@@walkergarya I don't see anything too controversial in that post. It's all fairly well supported. You may disagree of course, but that doesn't make you a liar. We all believe in something, good honest people can have different opinions.
it is great for home schooling
what is this music? ts fire. lmk rachel taylor
Literally doing this bs for studying and preparing for the Nyc state regents exam. And yes my yappertron Living teacher forced us to watch this😭🙏
