That semi conservative replication of DNA first demonstrate in E-coli

[@SchoolofBiologyy]

U are true

[@targetmbbs8353]

Yes it was left undiscussed 🤣🤣 !! Thanks

[@bettyfigi4263]

for q4 the nature of DNA replication is not semi-conservative and discontinuous because from the replication bubble it is clearly semi-conservative and semi-continuous. The leading strands on the left and right hands are both continuously replicated whereas the DNA in the lagging strand is discontinuously replicated and joined together by the DNA ligase. This means that it is partly continuous and partly discontinuous meaning it is option C.

[@genenedelelegn2316]

That's also my point.

[@jithink.v.6277]

Completely agree with u

[@kofipapa2886]

Spot on. He is dead wrong.

[@KaitokiNohara]

"Semi-discontinuous"

[@celinetws6922]

The dna strand which does not code for anything should be coding strand .(Q3)

[@randomhill3950]

Yes

[@surayyaazam1117]

Yes

[@omesabhat3727]

Exactly

[@uniqueworld8053]

Yes

[@adamamutalib3516]

Q 3. Is right (non coding strand ) but Q 4. Is wrong pls ( semiconservative)

[@mantsha5364]

Q.4 semiconsrvative right answer

[@bigtree802]

RNA polymerase is not involved in DNA replication but rather in DNA transcription.(question 8)

[@arunkaushik2121]

Primer kon lgayega ???
DNA polymerase alpha lgata h eukaryotes me, aur Prokaryotes me DNA- G protein, ye DNA dependent RNA polymerase activity show krte h, isliye inko RNA polymerase bola jaa skta h

[@KaitokiNohara]

​@@arunkaushik2121a seperate enzyme called Primase adds primer...some dna polymerase has both Primase and polymerase function

[@muhammadkhurram1327]

It's pretty good. Thanks for your help 😃😊😃.

[@scholartech9250]

During DNA replication, DNA helicases are used to cut the H bonds and pre replication protein complex cuts in oriC. So 18 answer is A) Helicase

[@anuragsonawane3101]

I also thought that

[@renutailorshorts8155]

Chemical knives are which enzymes cleave po4 bond between nitrogen bases but DNA helicase cut H bond

Where do we use rna ploymerase in replication...?Q's no .8 😬 can u plz explain

[@jyotimandal1217]

A will be the correct answer

[@priyankaraghuvanshi4171]

Yes mine question is also this ...where is RNA polymerase used in the DNA replication....it's function in the Transcription ....😒

[@chiamakaeneh4378]

Dna polymerase that replicates the template strand cannot start or initiate replication on it's own. Its requires a primer which is synthesised by RNA polymerase. Once the primer is made by Rna polymerase, Dna polymerase takes over the remaining replication process

[@aabidfarooq6522]

[@KaitokiNohara]

Comment section so assertive about "a strand that does not code for anything "...they say A.coding strand...dafug💀,the answer is correct ,its either non coding strand or non sense strand. If they were 10th grade and below i can understand tho.
And for those who said the denaruration temperature is around 90-94...rememebr the denaturation temp depends on how much G and C nucleotides the template contains.
Also Q.18 answer should be helicase..we don't use restriction endonuclease in dna replication...the answer should be helicase which seperates the two strands by breaking the hydrogen bond.
And the last answer is also helicase

[@Oranges46]

The denaturation of DNA : occurs in 60C°

[@ShabnasDesigns]

94degree

[@RajkishorNaik-r5c]

Thank yousir

[@SchoolofBiologyy]

Welcome

[@Saroch916]

Sorry sir RNA polymerase not involved in replication it's involved in transcription
And in replication involved RNA primase which form RNA primer

Question 8 is false
DNA replication includes:
DNA polymerase and ligase
It doesn't include (RNA polymerase)

All are include

DNA strand which does not code for anything is called coding strand ...not for the non coding strand. Your answer is wrong of 3 the number question...

4. Dna replication is semiconservative and semi discontinous

[@sejalgujrathi4200]

Listen , u should be responsible when u r reaching people.
Mistakes made in this video :
1) DNA replication is semi conservative and semi discontinuous.
2) DNA replication does not require RNA polymerase enzyme .
3) DNA is denatured at 90 degree Celsius.

Question 8 - what is the role of RNA polymerase in DNA replication. Your answer is D how?

[@SchoolofBiologyy]

primer Synthesized by primase which is a RNA polymerase type enzyme. it's mean RNA polymerase initially play a role in DNA Replication by making primer . but mainly RNA polymerase is involved in Transcription.

[@bunnylovers9877]

@@SchoolofBiologyy thanks for the explanation

[@SchoolofBiologyy]

[@chiamakaeneh4378]

Dna polymerase that replicates the template strand cannot start or initiate replication on it's own. Its requires a primer which is synthesised by RNA polymerase. Once the primer is made by Rna polymerase, Dna polymerase takes over the remaining replication process.

10 no question ka aap nahi bole kuch sir 🙏🙏🙏🙏

[@keshavaggarwal2410]

Semicontinuous and semi Conservative correct pls

[@SchoolofBiologyy]

Mention Reason in support of your Statement.

[@keshavaggarwal2410]

Because as you can see there is one continuous strand and one is discontinuous so answer is semicontinuous but you have marked discontinuous

[@SchoolofBiologyy]

Respected:
Replication occurs in 5 - 3 direction. Leading strand is also synthesize in 5-3 direction . it is cleared that replication is continuous . so we don't need to mention it . but surprisingly lagging strand is Synthesized in 3- 5 direction discontinuously . That's y we always says semi discontinueous replication.
Your point is also correct. appreciated ❤️👌🏿
