Genetic transformation of Escherichia coli with pGLO (Adapted from: Biotechnology Explorer: Bacterial Transformation: The pGLO System. Instructors Guide. BIO-RAD). Objectives a. To understand one of the most commonly used techniques for introducing DNA into E. coli cells and its use in molecular cloning. b. To become familiar with the concept of using green fluorescent protein (GFP) as a molecular tag for studying gene expression in bacteria and other organisms.

INTRODUCTION Levels of organization (cell to biosphere) and characteristics of life Levels: Cells->tissue ->organs & organ systems->organisms->populations->communities->ecosystems-> biosphere Characteristics of life: Cell and Organization: Each cell can only do the job it is tasked with. Example: brain cells Energy Use and Metabolism: Energy is needed many organisms. Energy is utilized in chemical reactions Response to Environmental Changes: responds to stimuli Regulation and Homeostasis: ex:

organic bases match up: adenine to uracil and guanine to cytosine. This is in accordance to the rules of organic base pairing. Once the mRNA has copied the DNA it floats of into the cytoplasm through the nuclear pores. This process is called transcription. Once the mRNA has passed through to the cytoplasm it attaches its self onto a ribosome or rRNA. This is the RNA that allows the mRNA to be separated into codons. Codons are three bases of the mRNA. Each codon once translated will mean

Conclusion 3.2.1 1 Describe how the DNA code is translated into messenger RNA. DNA is translated into messenger RNA through transcription and translation. DNA is split through transcription and then it is translated to match into RNA. 2 How is the RNA molecule a “script” for the protein production process? RNA is a script for the protein production process because they set the RNA up to translate into a protein. 3 What is the function of hemoglobin in the body? Hemoglobin functions in the body by

Tun-huang has its limitations‚ Yampolsky’s translation is—by far—the most accurate translation an English-speaking reader can find in this sect of Buddhist teachings. Yampolsky provides an accurate account of the Chinese language in this text‚ which retains a highly objective and scholarly approach to The Platform Sutra of the Sixth Patriarch in the later half of the 20th century. I would suggest this book as the pinnacle of Western academic translation for the teachings of Hui-neng in the Ch’an

molecular biology‚ "DNA makes RNA makes protein." Translation is the process by which RNA makes protein. In the cell‚ DNA makes messenger RNA (mRNA). mRNA travels to the ribosome which reads its sequence and makes protein coded to that sequence. In molecular biology and genetics‚ translation is the third stage of protein biosynthesis (part of the overall process ofgene expression). In translation‚ messenger RNA (mRNA) produced by transcription is decoded by the ribosome to produce a specific amino
