Members of a clone are genetically identical and genetic identity has given cloning an additional more technical meaning: namely the procedures used to create a new organism whose genetic constitution is a replica of another existing individual. Such a feat can be achieved by substituting the nucleus, which contains the genes, from one of the cells making up that individual's body, for the nucleus of a fertilised egg. Since our genes dictate to a large extent what .....

Words: 1552 / Pages: 6

.... is closely correlated with the increases in gross national product thus our economic development, the major sources of energy (that is fossil fuels) are 'stock resources'.

The quantity of ultimately recoverable fossil fuels is limited by geology and remains a matter of suspicion, but the view of the 1970s that scarcity was imminent is still popular. It is the 1973 Oil Crisis marked the transition from abundant, low-cost energ .....


The Effects Of Antibiotics On Bacterial Growth
Words: 1287 / Pages: 5

.... classification of bacteria is according to their need of oxygen to live. Those who do require oxygen to live are considered aerobes. The bacteria who don’t use oxygen to live are known as anaerobes. The shape of specific bacteria provides for the next step in the identification process. Spherical bacteria are called cocci; the bacteria that have a rodlike shape are known as bacilli; corkscrew shaped bacteria are spirilla; and filamentous is the term for bacteria with a threadlike appearance.

Mutations

.... two strands is complementary. The arrangement of the bases determines the genetic code of an organism. This code directs the synthesis of proteins at the cellular level. It is written in units called codons, each of which specifies a particular amino acid. (Proteins are composed of amino acids.) A codon consists of a sequence of three bases--for example, GAG or TCA. The four bases can be assembled into 64 possible codons. Because proteins are built from only 20 amino acids, most amino acids are specified by more than one codon. occur when one base is substituted for another or when one or more bases are inserted or deleted from a gene. Substitutio .....

.... start secreting digestive juices. If the trap closes empty, it will slowly open in about a day.

.... to each other. Receptors are special areas that receive these chemical messages. The key neurotransmitter in migraine is called serotonin (often referred to in the scientific literature as 5-HT or 5-hydroxytryptophan). If something interferes with the normal functioning (production, release, receptor docking, and/or re-uptake) of serotonin, that disrupts the normal functioning of the nervous system and can lead to various symptoms associated with migraine.
