Genetic Engineering

Genetic engineering is the process of changing the DNA composition in organisms using laboratory techniques.

Obtaining Recombinant DNA Using Vectors

Recombinant DNA is an artificial molecule obtained from organisms. The stages include:

• Locate the required gene and analyze its nucleotide sequence.
• Isolate the gene with enzymes that cut DNA into specific sections.
• Connect the gene to a transportation vector, such as virus DNA or bacteria. The combination of the gene and vector results in recombinant DNA.
• Introduce the recombinant DNA into the cell.

Polymerase Chain Reaction (PCR) Technique

• Heat DNA to separate the strands.
• Add DNA polymerase enzyme and nucleotides to the tube to synthesize complementary strands.
• Separate the formed strands

Reported Speech Transformation Exercises

• 4. Mrs. Prescott: “My daughter got married last year” (SAY) – Mrs. Prescott said her daughter had gotten married the previous year.
• 6. The student: “Could you explain number four, please?” (ASK) – The student asked if the teacher could explain number four.
• 7. The policeman: “Where do you live?” (ASK) – The policeman asked me where I lived.
• 8. Emma: “We went to the cinema and then to a Chinese restaurant” (EXPLAIN) – Emma explained they had gone to the cinema and then to a Chinese restaurant.
• 10. He: “Did you arrive before seven, Anya?” (ASK) – He asked Anya if she had arrived before seven.
• 11. He: “I would have visited the hospital, if I had known you were sick” (EXPLAIN)

1. What Is Static Electricity?

Static electricity is the imbalance of electric charge accumulated on an object’s surface.

It is commonly observed in daily life, resulting in phenomena such as:

• Hair rising
• A balloon sticking to a wall

2. Atomic Structure and Electric Charge

Electric charge is determined by the components of the atom:

• Proton: Positive (+) charge (located in the nucleus)
• Neutron: Neutral (0) charge (located in the nucleus)
• Electron: Negative (–) charge (orbits the nucleus)

Charge states are defined by the balance of protons and electrons:

• Neutral Atom: Equal number of protons and electrons
• Positive Charge: More protons than electrons (net loss of electrons)
• Negative Charge: More electrons than protons (net gain of electrons)

3. Methods

Power and Authority

• How is it used?
• What effects do the people in power have on others?
• What effect does it have on someone who has none?
  • Tituba
  • Does not having any power and authority make you an easy victim?
• How does fear increase the court's power?

Thesis

By exposing how power is protected through the scapegoating of the innocent, The Crucible critiques the way fear is weaponized to uphold authority and suppress dissent.

Supporting Arguments

• Thomas Putnam’s search for power by accusing people to get their land.

Control and Suppression

• Parris: "There is a faction that is sworn to drive me from my pulpit. Do you understand that?" (Miller 10)
• Those in power often use their authority to suppress opposition and protect their status.
• Parris is more concerned

The Collapse of the Soviet Union

Ronald Reagan served as President of the USA from 1981 to 1988. A staunch conservative and anti-communist leader, he renewed the arms race, which pressured the USSR and eventually contributed to its collapse. Mikhail Gorbachev, the final leader of the Soviet Union (1985–1991), attempted to save the nation through significant reforms:

• Perestroika: Economic restructuring focused on market economy principles and increased consumer goods.
• Glasnost: A policy of transparency, the abolition of censorship, and the introduction of democratic elections.

Causes of the Soviet Bloc Collapse

The crisis of 1991 had roots dating back to 1973. Key factors included:

• Economic Stagnation: The USSR failed to adapt to rising global energy

Core Entrepreneurial Concepts

Intrapreneurship

Intrapreneurship is the method of applying an entrepreneurial spirit within existing organizations, leveraging top-tier talent and resources.

Decision-Making Framework

The 6 Thinking Hats: This method prevents biased decision-making by separating emotions, logic, creativity, and structure.

Startup and Scaleup Definitions

• Startup: An organization designed to create a new product or service under conditions of extreme uncertainty. Startups are characterized by rapid growth, a technology-based business model, a lifespan of approximately 5 years, and an annual turnover of up to 5 million euros.
• Scaleup: A company that has moved beyond the startup phase, experiencing rapid growth while maintaining a scalable
