Biology 2A 2/23/14 Genetic engineering is making changes in the DNA code of a living organism‚ working almost the same. It has many purposes including clones‚ perfect humans and cures for genetic diseases. Gel electrophoresis is a powerful tool used for separation and analysis of macromolecules and their fragments‚ based on their size and charge. You place the DNA in the gel. DNA is a long‚ strand-like molecule where genes are written in genetic code. Extracted enzymes recognize and extract the

The main aim of laboratory work with Escherichia coli and soil sample was to introduce students to bacterial growth in pure culture and soil microbial flora. The experiment of bacterial growth in pure culture using optical density

Life on Earth 1. Analysis of the oldest sedimentary rocks provides evidence for the origin of life. Identify the relationship between the conditions on early Earth and the origin of organic molecules. - Conditions of early Earth: Massive oceans existed Only small landmasses above the surface of the water No ozone layer Large amounts of radiation reached the Earth No free oxygen in the air Large amounts of volcanic activity; heat‚ ash‚ dust and gases into atmosphere Violent electric

Spirulina The book wisely quotes Hippocrates who said‚ “Let your food be your medicine and your medicine your food.” Arthrospira platensis‚ commonly known as spirulina‚ is a filamentous cyanobacteria whose cells capture the energy of the sun and photosynthetically produce over 100 nutrients. The name Spirulina is derived from the Greek word “spira” denoting its open

· Taxonomy ○ Science of classification ○ Provides an orderly basis for the naming of organisms and for placing organisms into a category (taxon) ○ Makes use of and makes sense of the fundamental concepts of unity and diversity among living things ○ Basic principle is that members of higher-levels groups share fewer characteristics than those in lower-level groups * Escherichia coli - rod shape and have a Gram-negative cell wall * Even members of the same species display variations

Moon today. The Earth keeps the Moon in orbit by its gravitational pull it sets onto it. The Moon is constantly spinning farther away from the Earth at a rate of approximately 3.78 centimeters per year. When the moon was closer to the planet‚ days were only five hours long‚ now‚ since the moon is slowly spinning away‚ the days get longer‚ meaning that the days are now 24 hours and will continue to slow down. Without the Moon‚ the Earth’s rotation could slow down‚ causing the planet to wobble slightly

salty‚ called hypersaline‚ environments. They are able to survive in these extreme places where other organisms cannot. These salt-loving Archaea are called halophyles. Eubacteria‚ also known as “true bacteria”‚ are microscopic prokaryotic cells. Cyanobacteria‚ also called blue-green algae‚ are Eubacteria that have been living on our planet for over 3 billion years. Blue-green algae grow in the shallow parts of the ocean. Today it is only common in certain regions‚ but a few billion years ago‚ there

I recently backpacked 32 miles through the Grand Canyon National Park over spring break. My trip leader told me‚ “Sorry I made you guys pack so many warm jackets and clothes‚ its usually not in the 90’s during this time of year”. Just like that I thought to myself‚ I could have had a lighter pack but I also thought about how global warming is real and its everywhere‚ even in the vastest lands. Like astronomer Lucianne Walkowicz said and I mentioned in my previous paper‚ “the more you look for planets
