Ligustrum Leaf Cross Section. Evergreen ligustrum often called privet shrubs and trees thrive throughout the state of Florida. They are widely used as landscape shrubs, hedges, and specimen trees. Many species and cultivars are available with a diversity of leaf colors, leaf forms, and growth habits.

All selections are tolerant of heavy pruning, which makes them suited for clipped hedges. Because of a rapid growth rate, many require pruning to maintain them within bounds. The white flowers are attractive during late spring and early summer. However, the pungent odor may be objectionable. The nucleus plays the central role in cellular reproduction, the process whereby a single cell undergoes cell division and forms two new cells.

The nucleus directs the metabolic activities of the living cell and guides the life of the cell as long as it lives. They are composed of nucleic acid and protein. The chromosomes bear, apparently in linear arrangement, the basic units of heredity, called genes.

They are the code units of the transmission of bits of information from parent to offspring, and for the determination of the enzymes that so precisely regulate the myriad interdependent chemical reactions of life. Genes and Chromosomes - Biology: DNA in a Nutshell! DNA - From the Beginning. Primer on Molecular Genetics from the U.

Up to 3 fragments may be cloned at a time can you replicate that in the lab? Each fragment may be inverted relative to its original orientation. Genetic elements contained in the cloned fragments are transferred to the cloned DNA. We found an excellent Genetics tutorial: You will have to register to view it but it is free. A virus can multiply only inside a host cell, whose genetic mechanisms it subverts for its own reproduction.

Both the structure of the virus and its mode of replication differ widely between viruses. The usual outcome of a viral infection is the lysis destruction of the infected cell, with the release of viral particles.

Some viruses, however, can instead become integrated into the host chromosome, where their genes are replicated along with those of the host cell. Because viruses sometimes carry host DNA sequences from one species to another, they make possible an occasional mixing of different gene pools during their evolution.

Virulent viruses usually kill the cells they infect. Other viruses, although also often able to kill cells, frequently have a more subtle effect. These viruses are called temperate. Virus infected bacteria which appear un-infected but have the hereditary ability to produce phage, are called lysogenic. Upon infection, genes promoting both lytic growth and lysogenic integration are expressed. Which pathway succeeds is determined by the competing action of these early gene products and by the influence of host factors.

The lambda phage is a well studied temperate phage which can grow in synchrony with its host E. The lytic cycle is that part of the life cycle of a temperate phage in which it multiplies rapidly, destroying its host and releasing many copies into the medium.

The pathway genes in the lambda immunity region are: The lambda system provides one of the best studied examples of a genetic switch.

Two back-to-back promoters in the region of cI and cro control the genetic switch. When cI is present it activates its own synthesis and blocks transcription of cro. When cI is inactivated, transcription of cro can occur, resulting in the lytic cycle. The cI protein combines with the operator, Or.

Polymerase are enzymes producing a polynucleotide sequence, complementary to a pre-existing template polynucleotide. Polymerization is the combination of several molecules to form a more complex molecule, usually by addition or a condensation process. It is sometimes a reversible process.

The study of animals. The branch of biology that studies and classifies animals and animal life. It is a branch of biology that is concerned with the scientific study of animals, including their biology, distribution, and identification and including the study of animals - mammals, birds, reptiles, amphibians, fish, insects, spiders, and mollusks including mussels.

The science and history of the animal kingdom, including its king, the House Fly Musca maledicta. The father of Zoology was Aristotle, as is universally conceded, but the name of its mother has not come down to us. Two of the science's most illustrious expounders were Buffon and Oliver Goldsmith, from both of whom we learn L'Histoire generale des animaux and A History of Animated Nature that the domestic cow sheds its horn every two years.

OK, OK enough of the definitions - now tell me some zoology details. I want details please. Animals - Animal Kingdom Sites. University of Michigan - Zoology BiologyBrowser.
