Mam aap pr I mean unacademy Ritu mam ke teaching pr bhut sare students depend hai aur mam sabhi students fees pay nhi kr skte to mam aap please TH-cam pr ecology complete kijiye na mam aap bhut achha padhati ho mam aap ki teaching bahut jaldi samajh me aati hai I hope aap ecology TH-cam pr complete karengi please mam 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Mam Mai Unacademy channel pe sirf aur sirf aapke hi lectures dekhti hoo ❤️🌍Mam plzz aap hi pura syllabus complete karwaiye🥺Bio aap se accha kabhi koi nhi smjha sakta 😍💕you are the bessstt mam👑🥰
Mam u r just awesome...after studying with ur amazing diagram I don't know how I get all the points which I never forget...I wish I could find another teachers for physics and chemistry tooo just like u....😍😍

Thank u so much mam for uploading ur videos of biotechnology it's amazing fir s student to score 95 above in boards and crack neet and AIIMS ur r the only scope of my study else i don't have any option .. Payal.
I had never attended classes because I don't understand any topic on u tube first time I learn by utube and mam u are outstanding teacher as compare to my college teacher to understand things
Maam ur the best teacher reallly mam ur are great maine kbgi apke jaise teacher nh dekhi jo itna acha pda rhe ho plzz aap hi pura sylabus cover kr sakti hai plzzz
Mam your videos donot occur frequently.... Its my perspective that you teach really good comparatively....I think you should expand your videos like other teachers... 🙏
Why do restriction enzymes of bacteria not cut their own DNA? Why can it cut plasmids in genetic engineering, which are also part of the bacterial cell?...if methylation takes place in their own DNA...how can it cut its own plasmid DNA?? Doesn't methylation occurs on plasmid DNA??
Before this session, I thought this is such boreing nd difficult chapter.. but just coz of u ma'am finally I understand very welll!!thnks a lot ❣️❣️❣️❣️❣️❣️...
Before starting this chapter i do not have any idea about this chapter. As you are teaching so slowly to us we can understand better👌🏼@RituRattewal man so Thanku so much mam.. 🙏🏽and ( I need concepts not marks ) understanding is very important so once again thank you so much mam @Riturattewal #unacademy🙏🏽
Mam aap bhut acha padhate ho, or jyadatr bacche fees pay nhi kr skte to 🙏🙏🙏plz mam ecology krva do na, miss you mam, and wait for you mam (ecology) ..... You are great mam.

Thank you!!
Keep doing
Thanks...

Thanku bro ❤️❤️
Thank you bro ❤️
HIND I is first exonuclease restriction enzyme
HIND II is first endonuclease restriction enzyme
thats why first endonuclease is given roman number II because exonuclease and HIND II is first endonuclease
It means First Restriction Enzymeis Hind l And first Endonuclease Restriction enzyme is Hind ll Is It right?
@@Shivshambhu098 yes right

Oh thanks for saying yaar
Mam u should make a book of yours with these illustrative diagrams. u rock

Roman number does not indicate the order of discovery. It indicates the order of isolation of the restriction enzyme from the particular strain of a bacteria.
Since Hind-II was discovered earlier than Hind-I, that's why the first discovered restriction enzyme is Hind-II. But Hind-I was first isolated from that strain of bacteria from which Hind-II was isolated later. That's why there's II in the first discovered endonuclease enzyme.
Mam aap se axa koi padha hi nahi sakta ❤️❤️❤️❤️

Amazing lecture.... Seriously ma'am no one can teach like you... You are a phenomenal teacher.
Roman no. Indicates the order of isolation of restriction enzyme from particular strain ,not the order of discovery
Best bio teacher of world....... 🤔😘🙏🙏🙏🙏🙏
THANK U MAAM!!! UR NOT SLOW NOT FAST IN TEACHING !!! UR IN THE CORRECT SPEED REQD!THANK U SO MUCH!
Bleesed to have u dear ma'am ❤️❤️❤️ .... U always Rock ❤️❤️🔥🔥

Roman numbers indicate the order of isolation.
Hind II was discovered before Hind I but it was isolated from the cell after Hind I.
Ma'am aap India k no. Biology teacher ho❤️❤️😘❤️❤️😘❤️❤️
Which of these following is the first restriction enzyme...
A..Ecoli. B...EcoR1. C ....Hind 2. D ....Hind . .

sometimes plsmid do depend on bactereial cjromosomes. such plasmid are called as stringent plasmid they can produce only 2 or 1 copy number.

Mam you are best teacher of biology comparison to class teacher of biology🙏🙏👍👍💥💥❤❤💓
Mam you make every topic of biology so easy 🥰🥰🥰🥰
Best teacher ever❤
Thank you mam for clearing My all doubt mam you are amazing
Mam if there is restriction endonuclease in bacteria then how does bacteriophage destroy it and undergo Lytic/ lysogenic inside it
Hind 2 is first restriction enzyme because hind 1 cut randomly on DNA strands
No doubt ma'am your are the best teacher of biology 😎👍🏻
Thank you so much Ma'am for wonderful session ✌️

U r the best teacher 😍💯 of the world
Mam you are amazing 🤗🤗🤗🤗
U are amazing man ❤❤
Mam, from 230 strains of bacteria there must be only 230 restriction enzymes but why there are more than 900 ???
Many restrictions enzymes can be obtain from single bacteria
Thank you so much mam for explaining so well🙇♀️🙏... May God bless you always mam😇🌼.... lots of love and respect to you!❤❤
R..uh studying for term 2 😇😇
Mam am so thankful for your amazing lecture.. Love you so much ❤️❤️
because roman no. doest indicate the numerical order.....instead indicates the order of isolation
King of biology
Very nice explanation mem ji...

Roman numbers indicate the order in which the enzymes were isolated…so hind 1 was isolated first but was discovered after hind 2
