Ma'am these videos are just a blessing for all the students. I've fallen in love with learning all because of you.
You were born to become a teacher. You were born to do this ❤❤
2025 Boards😂
Great conceptual and detailed explanation.
Thanks a lot!
It's a reality that Roshani mam is multi talented women in the world 🌎
57:09 what 😂
Pta kaise chalta h mam ki vhi fragment bind krega plasmid ke sath 🤔🤔🤔
No doubt mam aap acha padhate ho lekin aap ki video se notes banana thoda difficult hai 😅
1:05:18 wont the transformants not grow as it doesnt have resistance and the non transformants be allowed to grow as it has resistance?
Actings wallah
Board exam 25-26🎉
Thankyou mam❤
Thankyou mam❤🎉
Thank uh for teaching this ch in very short time period as comparison to others , it was easy to understand! thank uh soo much❤
Wonderful lecture ma'am thankyou so much
Thank you very much mam
Mam the concept of selectable markers is well understood
This one shot video is best for this chapter explained so well ❤
Supper ❤ explanation mam thank you so much 😊🥰❤❤❤
🤩 Amazing lecture ma'am
Thankyou so much 🫶🏻
Every single concept is crystal n clear ❤
Thank you so much mam …
Concept is crystal clear 😊
mam your example of jellyfish and frog is really work in real science….?????
Mam question bhi krwa dijiyega na by CBSE pattern
Love it ❤❤❤ best teacher
Loved the class, you made it much more easier to understand even though I don't speak hindi. Plus I didn't quite understood abt the polymerase chain reaction,now everything is clear thanks to you ❤
I am Malayalee This class was superb and the biotechnology chapter was very difficult according to me but the ma'am class was understood So very nice class ❤❤❤❤❤❤❤❤❤❤❤❤❤❤
