Chapter 6.1: DNA Replication

This video explains in detail the semi-conservative nature of DNA replication and how DNA replication occurs. Students will learn how the nucleotides pair up in DNA and RNA and will also learn about the different enzymes involved in the DNA replication process.

Your videos are very help, love it! would love it if you could go through some A2 past paper Qs too!

[@devivivekanand9208]

Could you please post the videos for the remaining chapters, it would be of great help! Thank you :)

[@biowithdrdemi]

Hi Devi, certainly! I am getting them ready

[@isaferr8291]

Dr. Demi YOU ARE THE BEST!!

[@joyakua2063]

Thank you soo much. You made it very simple for me

[@SakuraLee_San]

Thank you so much for thissss, great review right before AICE exams T^T

[@aash2324]

this video saved my life!!!
THANK YOU SO MUCHH

[@seekerri322]

I SWEARRRR

[@dahabdaoud345]

Hey Dr Demi i don’t understand what the point of the RNA primers are if we’re talking about DNA replication - can you please explain why there’s RNA involved in DNA replication.

[@Physics-Momentum]

Hey
What’s the role of the nucleoside triphosphates then.. Are they the same as RNA primers?

[@rockybeez3087]

Thank you Ma'am, you're videos are very good

[@seekerri322]

Doctor demi why are u sad in this video :(( ik DNA chapter is such a hastle but if we stick together we shall make it out alive as a team

[@lilnigga9622]

Lol

[@foodvlogs4504]

Thank you so much mam for this lecture .

[@mellow1611]

hi Dr Demi i dont understand like our bopok is written that there is DNA ligase
.....is it the same as pimosome

[@biowithdrdemi]

No it's not. The primosome creates RNA primers but that's beyond the scope of the syllabus.

[@sarahrahman7901]

Hello!
On the DNA replication, the 3rd bulletin point, Is it leading strand in a 5' to 3' direction or 3' to 5' direction.
Since you mentioned LEADING STRAND, I suppose its 3' to 5'.
Thank you.

[@biowithdrdemi]

Hi Sarah, yes the leading strand is 3' to 5'

[@owaisahmed5265]

So DNA polymerase runs in opposite direction of leading strand?

[@chrissycoolcat]

@@biowithdrdemi isnt it 5' to 3'?

[@hazramarwa1341]

YOU ARE THE BESTTT :)

[@gothellee]

Heyyy , are we required to know how to draw/identify the different bases by their structures such as adenine , cytosine etc

[@biowithdrdemi]

Yes you should be about to identify them. I've never seen a question where you're asked to draw them

[@flawedoptimist5812]

Hi ! I had a question are your lectures according to the new syllabus? (2022?)

[@biowithdrdemi]

The differences are very few. Things have been taken out of the new syllabus, nothing new has been added so the videos still cover everything you should know.
