Introduction In this week’s laboratory period students had the opportunity to perform a common procedure preformed by many if not all microbiologists known as genetic transformation. Genetic transformation is the ability to move DNA into an organism and thereby altering its genotypic and genetic makeup (2). Genetic transformation has shown to have a wide variety of uses in many scientific studies. In agriculture‚ gene coding for traits such as frost‚ pest‚ or spoilage resistance have been genetically

Type of cancer. Melanoma is a skin cancer that originates in the melanocytes‚ a type of cell that makes up the skin. Skin is formed by three layers: epidermis‚ dermis and subcutaneous tissue. Melanocytes‚ together with keratinocytes‚ are part of the epidermis and are responsible for producing melanin‚ a pigment that protects against the damaging effects of sunlight. The formation of melanin - melanogenesis is a biochemical process carried out by melanocytes and is affected by several hormones: α-melanocyte-stimulating

You are at increased risk of developing melanoma if there is a family history of melanoma in one or more of your first-degree relatives like a parent‚ child‚ brother or sister. The major environmental risk factor for melanoma is overexposure to ultraviolet (UV) radiation from the sun. People who have fair skin that burns or freckles easily need to be especially careful in the sun as protecting yourself against UV overexposure is an important way you can help reduce your risk of developing melanoma

and thus allowing the buildup of free oxygen in the air. As oxygen moved into the early atmosphere‚ ultraviolet radiation from the sun split the oxygen molecules (O2)‚ which then recombined‚ producing the Earth’s ozone layer (O3). This‚ in turn‚ reduced the amount of incoming ultraviolet radiation striking the Earth. The impact for life on Earth was enormous. With reduced amounts of ultraviolet radiation‚ organisms moved to shallow water and‚ ultimately‚ onto the land. Materials: Elodea stem
