DNA Polymerase vs RNA Polymerase

DNA Polymerase vs RNA Polymerase - this lecture explains about the difference between DNA polymerase and RNA polymerase. 1.DNA polymerase synthesizes DNA while RNA polymerase synthesizes RNA.

2.In contrast with the DNA polymerase, RNA polymerases do not necessarily require the so called primer to start the process and they actually have no proofreading systems.

2.RNA polymerases are capable of initiating a new strand but DNA polymerases cannot.
5.DNA contains the pentose sugar deoxyribose while RNA contains the pentose sugar ribose.

6.DNA polymerase will be continuous till the work is finally done wherein RNA polymerases will continue but eventually may break in the event it will reach a “stop” cycle.

7.Subunits contained in RNA polymerases must unwind the templates of DNA and the DNA polymerases do actually abide the helicase that the double helix may be open just in front of it.

8.Lastly, DNA polymerase is a lot faster compared to RNA polymerase.

You're awesome, Shomu, the best teacher, a brilliant mind. I admire you! Regards!!!

[stephanielee]

Provided exactly the clarification that I was looking for, along with related high-yield facts in a succinct video. Thanks!

[lenircotia]

Very well explained and the only video on youtube on DNA- vs RNA-Plolymerase! Thank you!

[MatildaDeme]

great job Shomu, I like the way you break down and the explain every point in deep details.
Thank you very much.

i need to pass this test to get an a and thank god for this man, for real gonna save my entire AP bio career

[abby]

exactly what I was looking for. clear and concise. thank you!

[andiefowler]

thank you!! you made these concepts so much more clear and helped me a bunch

[jeff-freehoke]

Very good job. Please keep doing what you are doing. I hope you are benefiting personally from these wonderful videos.

[sovereignconfluence]

Very good and concise explanation of the basic differences. Great job!

[anusmita]

You are best teacher for me..bcz i can clear my concept after watching ur videos..nd now m starting to like my own subject biotechnology..its too difficult..but too much easy, after watching ur lectures..thnk u sir..

[alnashraansari]

thank you so much shomus for explanning the differnce between DNA s RNA polymerase

[cherryen]

Thank you for this. It cleared up a lot of confusion. Subscribed 👍

You Are Amazing these words beginnings form (UAA) a stop codon hehehehe allah wish you all the best in your life...bro keep going

[cyfan]

Thank you so much for explaining the differences! Much appreciated!!!

[chalaniruchirawelaratne]

watching from SRI LANKA. THANK YOU VERY MUCH

[sadatsadat]

Amazing ! I wish you could tell about termination and a bit more about the function of RNA and DNA polymerases

[gabrielb.]

I'm from brazil and your video was very useful. Thanks bro!

[joshuagibbygibson]

Great video bro. I like your popped collar swag!!😎
