1B) Promoter Mapping
Hypothesis: The promoter is upstream from the TSS (Transcription Start Site).
Reagents/Assays:
First, clone β-globin & cDNA. Then, identify the TSS by comparing the cDNA and gene sequence of the DNA. The promoter is then mutated one base at a time using PCR site-directed mutagenesis, creating approximately 250 mutated DNAs. Transfect eukaryotic cells with the promoter and measure the transcriptional activity of a reporter gene via mRNA or protein activity.

Human Migration Patterns: From Africa to Global Settlement
Human Origins and Global Dispersal
Through the use of scientific methods such as paleontology, archaeology, and genetics, Africa has been established as the cradle of humankind. Through evolution, humans were able to venture outside Africa. The discovery of fire by Homo erectus revolutionized hominid life, enabling human beings to venture into cold areas outside the warm continent of Africa.
Early Hominid Migrations
Around 1.5 million years ago, hominids began to spread out of Africa (Tignor, 2010)

The Sustainable Management of the Planet: It is necessary to civilize humanity in its relationship with nature. Our future depends on the decisions we make.
Development Model
This model is characterized by the belief that the planet’s resources are unlimited. It does not consider the environment as part of its conception, viewing nature as something to be subject entirely to man. This development thinking has been, and still is, widely used worldwide.
Conservation Model
This model emerged from the limits

Spanish Lyric Poetry: Evolution from 1970s to Today
Introduction to Contemporary Spanish Lyric Poetry
With the death of dictator Francisco Franco in 1975, Spain began its transition to democracy. Key milestones included: the legalization of political parties in 1977, the promulgation of the Constitution in 1978, an attempted coup in 1981, and entry into the European Community in 1986. Key characteristics of Spanish literature in recent decades include a wide thematic and aesthetic range, diverse literary trends and movements, and a proliferation of

Fatty Acid Oxidation
Fatty acids carry more energy per carbon because they are more reduced. They also carry less water along because they are nonpolar. In contrast, glucose and glycogen are for short-term energy needs and quick delivery, with fat stored in adipose tissue.
Lipids are transported in the blood as chylomicrons. Unsaturated fatty acids have a bent structure.

- Glycerol kinase activates glycerol at the expense of ATP.
- Subsequent reactions recover more than enough ATP to
