DNA Transcription The process of transcription is where a copy of a gene is made within DNA to use as RNA. It is located in the nucleus of eukaryotes and in the nucleoid of prokaryotes. DNA stores information encoded in a genetic code. The code consists of four letters and they are T (thymine)‚ G (guanine)‚ A (Adenine)‚ and C (cytosine). One gene codes for on protein. RNA is a molecule that copies information that is coded in another genetic code. This code also consists of the same four

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA is a polymer‚ which is a chemical compound or a mixture of compounds consisting of repeating structural units. These repeating structures are created through polymerization. The monomer‚ meaning one part‚ units of DNA are nucleotides. Each nucleotide consists of a five carbon sugar‚ also known as deoxyribose‚ and nitrogen containing base attached to the sugar

Despite continuous improvements and modification to the technique‚ DNA microarrays are still no more than a glass microscope slide studded with individual immobile nucleotide fragments (1‚ 2). The fundamentals of DNA microarrays are set on complementary base-pairing (3)‚ and because the exact sequence and position

A. Introduction A banana is an edible fruit produced by several kinds of large herbaceous flowering plants in the genus Musa. (In some countries‚ bananas used for cooking may be called plantains.) The fruit is variable in size‚ color and firmness‚ but is usually elongated and curved‚ with soft flesh rich in starch covered with a rind which may be green‚ yellow‚ red‚ purple‚ or brown when ripe. The fruits grow in clusters hanging from the top of the plant. Almost all modern edible parthenocarpic

Banana (Musa spp.) is one of the most produced and widely consumed by worldwide market; and was originally descendent from hot and tropical region in South East Asia. For over 200 species were discovered which contributes to various cultivar with different types of characteristics and appearances tagged along the traits (Salunke‚ 1984). Banana came from family Musaceae genus and scientifically named as Musa paradisiacal L. In Malaysia‚ the diversity of banana can be proofed by the cultivars of diploid

A fruit grown throughout the world in temperate climates for at least 3‚000 years‚ there are now thousands of varieties from yellow to green to red‚ tender to crisp‚ sweet to tart and simple to complex. The apple tree and pear tree are related to each other--They are both part of the rose family. "Baking" apples are varieties that hold up well when cooked and don’t turn mushy. Good baking apples are: Rome Beauty (Queen of the bakers because cooking accentuates its flavor) Golden Delicioius (holds

NUTRIENTS IN BANANA PEELS Banana peels are also rich sources of potassium and contain much more soluble and insoluble fiber than their flesh. Dietary fiber promotes digestion and bowel movements and can reduce blood cholesterol levels. Banana peels also contain tryptophan‚ which increases serotonin levels in the body and affects mood‚ much like the drug Prozac does. According to "Prescription for Nutritional Healing‚" researchers in Taiwan discovered banana peel extract can ease depression because
