This document discusses cloning techniques including cloning plants from single cells and cloning animals using embryo splitting and nuclear transfer. Embryo splitting involves fertilizing an egg in vitro, growing it to 8-16 cells, separating the cells, and transplanting them into surrogate mothers. Nuclear transfer removes the nucleus from an egg, fuses it with another cell, and transplants the embryo into a surrogate. Dolly the sheep was the first mammal cloned using nuclear transfer. Gene cloning involves using restriction enzymes and vectors like plasmids to multiply copies of a gene for manipulation. Steps in cloning a single piece of DNA include isolating the DNA fragment, ligating it into a cut vector, transforming bacteria, and confirming the recombinant plasmid.
In biology, cloning is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects or plants reproduce asexually. Cloning in biotechnology refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms. The term also refers to the production of multiple copies of a product such as digital media or software.
Cloning is the process of producing genetically identical individuals of an organism either naturally or artificially.
It is the process of taking genetic information from one living thing and creating identical copies of it. The copied material is called a clone.
Nature has been doing it for millions of years. For example, identical twins have almost identical DNA, and asexual reproduction in some plants and organisms can produce genetically identical offspring.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
6. Embryo Splitting
• Egg collected
• Fertilized by in vitro fertilization (IVF)
• Embryo is grown to 8–16 cells
• Cells are separated
• Separated cells grown into separate embryos
• Embryos transplanted into surrogate mothers
• May be used to clone any mammalian embryos,
including humans
9. Nuclear Transfer
• First done in 1986
• More difficult
• Nucleus is removed from an egg
• Enucleated eggs are fused with other
cells
• Embryos are transplanted into a
surrogate mother
• In 1997, Dolly the sheep was the first
mammalian clone from an adult donor cell
12. Problems -
don’t live as long
not carbon copies/identical
develop diseases early
very low success rate - 0.1 - 3%
Dedifferentiation/reprogramming may not be complete
or accurate
13. Gene Cloning
All identical to starting gene - CLONES
Gene
Host
Cloning vector Recombinant DNA
Started with: few copies
GOAL: To get enough copies of the gene to manipulate
Multiply
Ended with: Many copies.
17. Frequency of occurrence of restriction sites
If DNA sequence has equal amounts of each base
If bases are distributed randomly
6 base cutter (1/4)6 = 1 site in ~4000 bp
4 base cutter (1/4)4 = 1 site in 256 bp
23. EcoRI EcoRI EcoRI EcoRI
4.0 kb 2.0 kb 3.0 kb
Problem: How to get the 2.0 kb piece to subclone into
vector
Randomly
Isolate specific fragment
Shotgun cloning
24. Steps in cloning a single piece of DNA
1. Appropriate restriction sites
2. Cut vector and foreign DNA with RE
3. Run on gel to separate fragments
4. Isolate specific fragment
5. Ligate with cut vector
6. Transform host bacteria. Selection.
7. Grow up colonies.
8. Isolate plasmid DNA.
9. Cut with RE to confirm presence of foreign DNA.
10. Run on gel to identify recombinant plasmids.
28. Selecting Cells with Vectors
Vectors carry antibiotic resistance genes
Growing antibiotic-sensitive cells on media with
antibiotics ensures that all growing cells must
carry the vector
Selecting Cells with Recombinant Vectors
While inserting the donor DNA, an existing gene
in the vector is inactivated
OR
In addition to the Donor gene a marker gene is
added
29. Original vector - 4 kb with one RE (EcoRI) site
DNA to be inserted - 2 kb, flanked by same RE
Cut plasmids isolated from colonies. Run gel
Vector alone (no insert) - 1 band
4 kb
How to tell that plasmid now contains insert
Vector + insert - 2 bands
4 kb AND 2 kb
