For 9th grade general biology: A very basic animation of DNA replication for high school students. You might want to watch my “DNA in a nutshell” before watching this. You might want to watch my “Transcription” animation after this one.

Or, for access to this single video, go to: www.mindbites.com In this lesson, Professor Wolfe provides a complete overview of the replication of DNA, beginning with its structure. DNA has a double-helix structure of nucleotides, which made-up of a sugar, a phosphate, and a base. The strands are antiparallel, meaning they run in opposite directions, known as the 5′ strand and the 3′ strand. DNA replicates by the semi-conservative method of replication. Professor Wolfe explains how DNA polymerase only reads in one direction, from 3′ to 5′, and therefore creates “”replication bubbles”" in order to replicate the DNA twice as fast. This creates leading and lagging strands, which require RNA primer and Okazaki fragments added to the lagging strand in order for the process to work properly. At the end of the strands, which lack the free OH molecule needed to complete the process, telomeres are used to protect against a loss of information. This lesson is perfect for review for a CLEP test, mid-term, final, summer school, or personal …

Great videos, thanks to you im getting a 70
Recent studies show that positive emotion/thought such as love, joy, greatfulness and etc. effects human DNA by making the strands longer and more perceptive (meaning uncoding the hidden talents such as ESP, precognition, clairvoyance and others), when negative emotion such as fear, anger, despair and etc. makes DNA shrink, therefore limiting human perception a great deal. One has to establish an ongoing positive thought in order for these change to occur.
when the exams come around, im just going to draw this man
u r great …
this is amazing ! haha they’re trying to teach us science at an arts school, so this was veryy helpful ! (Y)
She is so sexy and Latino women rockmycity.info
i love you.
very good teacher
thank. you. its really hard to be prepared for a test when you leave your book in your locker…..
my only question is: why HAS the other side has to be antiparallel? there wouldn’t be a problem if it went in the same direction, I think..
nice. the crazy old bastard explains things quite well.
@VthatsME it has to do with getting the bases to line up (adenine+thymine and guanine+cytosine) its just the way the molecules fit together.
How much does each lesson cost?

@cutieme44
I teach high school students. They love it.
I’m in 9th grade, I have a test on this Monday for Biology class, and this was helpful. Thanks
ya im in grade 9 too and have a test tomorrow on this soo usefull thanks!
@cutieme 44 (NOT)
1) Read the summary; very basic annimation
2) hit the mute button
3) learn replication the first time around, not when your 30 or whatever the age (chronologically, not mentally) over 13 you are.
@MrBiology1 well maybe you should suck my dick, that might help
I think this could have used a little more info. leading strand? lagging strand? Very vague.
