Blue White Screening | CSIR NET- Life Sciences | GATE Exam
The blue-white screen is a screening technique that allows for the rapid and convenient detection of recombinant bacteria in vector-based molecular cloning experiments. DNA of interest is ligated into a vector. The vector is then inserted into a competent host cell viable for transformation, which are then grown in the presence of X-gal. Cells transformed with vectors containing recombinant DNA will produce white colonies; cells transformed with non-recombinant plasmids (i.e. only the vector) grow into blue colonies. This method of screening is usually performed using a suitable bacterial strain, but other organisms such as yeast may also be used.

Amazing mam ... Best explaination ever for genetics...👍
Ma'am will you please explain us "red-white selection" of YAC.
Very very important and informative video. Thank you
thanx didi..whenever there are doubts , i come to ur channel
The way you teach & describe the molecular events is really fascinating & so easy to visualise. Keep up the great work mam. 😇😇😇👍👍👍👌👌👌💜💜💜

This was by far the best video on bluewhite screening. I was really confused and nervous about this topic but you made me understood sooo well. Best teacher ever.
You had the best explanation Thank-you ma'am
best video to understand this topic❤
Thank you so much 💕 ma'am. You give me the concept that i never understood before 💯
Best teacher on KZread ❤️
Thanks a lot mam, your explanation is great, & finally give a clear concept.
Great teaching
Thnks mam 🥰 🙏 .stay home stay safe . N we are hpppy u 2 say also safe .....
Thanks ma'am, you helped a lot. Your video gave me a proper concept.
Well explained ✌️nice🌹
Well explained! 😍
thankyou mam the thing you have done in 10 min my teacher had taken a week to explain same thankyou soo much mam🙏🙏

Mam blue white screening and x-gal dye for selection of Recombinant population..is same ???
Where can we get the possible notes for this particular topic?
Mam gene of interest hmesa lacz ke bich me hi insert hota h kya ? Ampicillin ya tetracycline ke bich ni hota h..
Those cells which are non transformants will also give white colonies bcz they dont have lac z So how do we distinguish non transformants from transformants who have undergone recombination
Thanku mam ❤️❤️
Thanks ma'am
happy teachers day mam
Thanks
Thankuuuuu sooo much mam,❤️❤️
Thank you ma'am
Can u make video about corona virus or may be how any virus propagates ,cycles and virulity factors
Thank you Didi
Mam apne lacz gene ka explain kiya and then blue white screening ko differetriate kiya tu kya hum ampicillin or tetracycline gene ke base per blue white screening ko differetriate kar sakte h kya?
mam pls make video on DNA sequencing 🙏🙏
Thanks mam
blue colour colony includes transformed ( self ligated in which gene of interest not inserted, i.e; non recombinants) and non transformed ,how we will distinguish transformed from non transformed in blue colony

No... Blue colour colony only include non transformed i.e self ligated bacterias.

@@gururajkalshetti198 Transformation is the uptake of DNA by bacteria. If you're saying its non transformed, that means bacteria didn't uptake that plasmid vector, then from where did the blue colour came??

Transformed and non transformed selected on the basis of selectable marker ( vector)and antibiotics ( culture media) only transformed colony are grown on culture media

Ma'am a transformed host (recombinant) and a non transformed cell both dont produce blue colour means white colour is retained as usual Now how can we select the recombinant from non transformant Plz reply ma'am
madam bahat achha laga.madam ap kon state me rahate haee??
How to join your telegram group. Link is not given
But mam Non Transformed or transformed with no gene of interest same color denge???then dono ko kse separate kre plzzz bata dee
Telegram ki link open nai ho rahi hai ma'm
Hello mam, here how we will differentiate between recombinant and non transformed cells. Self ligated cells will appear blue in colour but what about non transformed cells how it will be differentiated from recombinant cell. Please clearify

White colour colonies because Lac z gene contains Cloning sites where our Gene of interest gets inserted resulting into disruption of Lac z gene. So now if lac z gene is disrupted, there will be no beta galactosidase production, and thus no conversion of X gal, and thus white colonies.
mam can u please teach genetic code from molecular biology
Can anyone tell Can distinguish non transformed from recombinant transformed cells. As both will give white colony?

This video is confusing. Transformation is necessary in every aspect. If there's no transformation we won't even get Blue colonies. Then comes Recombination, if your Plasmid Vector contains your gene of interest in the Lac z sequence, beta galactosidase won't be produced as the Lac z gene is disrupted by your Gene of interest thus you'll get white colonies. If your vector doesn't contain your gene of interest, that means the Lac z gene is intact which will produce beta galactosidase giving blue colour colonies. Recombinant- White colour colonies. Non recombinant- Blue colour colonies. And non transformants means bacteria didn't uptake your plasmid vector.
The bacrerial cells without any kind of uptake of vector(totaly non transformed) will also produce white colonies, so how to discriminate??
