In this Video, Ms. Poonam Rajawat, Assistant Professor, Biyani Group of Colleges, describes about virus plaque assay. It is an assay to enumerate phage particle on solid agar media. A clear area formed on agar media known as Plaque. It is a double layered technique. Phage dilution was prepared in trypton broth and two drops of E. coli. were added when bacteriophage affect the bacteria, it causes lytic cycle and form plaque.

In this Video, Ms. Deepika Rathore, assistant professor, Biyani Girls College, Jaipur, explains about the initiation step of Eukaryotic DNA replication, in which the ORC recognize the ARS and when ABF1 binds at B3, melting starts at B2 with the help of helicase and T-Ag protein. The Okazaki fragments are formed by the pol α and the leading strand is formed by the Pol δ which is called pol switching.

The lecture includes DNA sequencing procedure by Sanger. The process involves the termination of DNA replication by the use of dideoxy nucleotides made of four different bases of DNA. It involves the DNA polymerisation by the PCR but the reaction mixture consist of primer, dNTPs, DNA template, buffer, DNA polymerase and ddNTPs consisting of pentose sugar lacking –OH group at 3′ position. The chain extension takes place till the DNA polymerase do not encounter ddNTPs. After PCR the products are analysed on AGE and finally sequenced from bottom to up.

In this video Ms. Aastha Pareek, Biyani Groups of colleges, Jaipur, explains about differences between Lanthanides and Actinides.

It is a part of lecture presented by Pragya Dhakar, Assistant Professor, Biyani Group of colleges. On behalf of Gurukpo this lecture discuss about the modes of nitrogen excretion in different life forms i.e. Ureotelic ,Ureicotelic, Ammonotelic and main emphasis has been given on the ureotelic mode wherein the amino nitrogen is removed in form of urea. Further urea cycle is discussed in detail.

In this Video, Ms. Ankita Maan, Biyani Groups of Colleges, Jaipur, is explaining about hypertension. Hypertension is a condition in which the arteries have persistently elevated blood pressure. The higher the pressure the harder the heart has to pump.
