P1-derived artificial chromosome PAC n. One type of vector used to clone DNA fragments to kb insert size; average, kb in Escherichia coli cells based on the phage P1 genome. The stage of Prophase I during which the two sister chromatids of each chromosome separate from each other.


During this stage, the chromosomes look thicker when viewed under a microscope pachys is Greek for thick. Homologs are still paired at this point. Pachytene is also known as pachynema. Non-sister chromatids remain in contact throughout pachytene and a kind of localized breakage of the DNA occurs, which is followed by exchanges of DNA between them.

This process is called crossing over. Crossing over produces "cross-over chromatids ," each composed of distinct blocks of DNA, some blocks derived from the mother, others from the father. A mammal belonging to the erstwhile taxonomic group Pachydermata meaning "thick skinned ones". This group included elephants, certain artiodactyls, such as hippopotamuses and pigs, as well as some perissodactyls rhinoceroses, horses.

The roof of the mouth; the bony portion is the hard palate, the fleshy rear portion is the soft palate. An epoch of the Paleogene. It lasted from A formerly existing continent, now broken up or fused with other continents due to the effects of rifting and continental drift.

The first period of the Cenozoic Era. The Old Stone Age. The Paleolithic was the first period of stone tool use. It extended from the time of the earliest known stone tools, about 2.

The scientific study of the life of past geological periods. The first, and most lengthy era of the Phanerozoic Eon. It lasted from to million years ago, and is composed of six geologic periods, which are, sequentially, the CambrianOrdovicianSilurianDevonianCarboniferousand Permian.

Nearly all of the various plant and animal phylawith the major exception of the angiospermsfirst became abundant during the Paleozoic. Application of the hands to the external surface of the body for the purpose of determining the state of an underlying organ or tissue.

The genus to which the chimpanzee Pan troglodytes and the pygmy chimpanzee, or bonobo Pan paniscusbelong. A large gland, situated behind the stomach in humans. Its thicker end the "head" is attached to the duodenum. Its slimmer end the "tail" extends as far as the spleen.

The pancreas produces an internal and an external secretion. The internal secretion, or "pancreatic juice," which plays an important role in digestion, arises from the cells of the acini and passes through a network of ducts to the duodenum.

A single great supercontinent that existed from the Permian to the Jurassic. It broke up to produce all of the modern continents.

The genus comprised of the big cats, the lion Panthera leothe jaguar Panthera oncathe leopard Panthera pardusand the tiger Panthera tigris.

Surgical removal of a papilla. A raised, red bump on the skin; the term is applied to any bump up to about the size of a pea. An inversion that does not include the centromere.Details of the scientific research and corresponding epidemiological studies on wireless health effects ranging from infertility and cancer to insomnia, arrhythmia, and neurological disorders.

Introduction: The formation of adsorbed “protein corona” (PC) on nanoparticles could influence particles’ biodistribution, cellular uptake and toxicity, thus has drawn attention in recent years.

The composition of PC on lipid-based nanoparticles (LNPs) is dependent both on the particle specific factors (e.g., surface chemical composition) and biological factors (e.g., different.

The 'lampbrush' phase of extended chromosomes during meiosis has also been suggested to enable forms of genetic re-processing. In non-mammals this extended phase involves open transcription of coding and non-coding regions and has been proposed to be a form of genetic processing (Wolfe R), which probably occurs in a less obvious way in mammals as well.

SALINITY TOLERANCE IN TOMATO ABSTRACT: Growth and fruiting of five cultivars of tomato viz., Tropic, pearson, Monte Carlo, ACE and Strain B were studied at different salinity levels ranging between mM NaCl.

Since the introduction of cisplatin to oncology in , Pt(II) and Pd(II) compounds have been intensively studied with a view to develop the improved anticancer agents.

Polynuclear polyamine complexes, in particular, have attracted special attention, since they were found to yield DNA adducts not available to conventional drugs (through .

The genetic information in the DNA determines the specific sequence of amino acids and the specific protein that is produced. Proteins are examples of one type of biological polymer.

Along with proteins, carbohydrates, lipids, and nucleic acids constitute the four major .
