Evil Women and Innocent Victims: The Effect of Gender on California Sentences for Domestic Homicide Ryan Elias Newby* I. INTRODUCTION Karen Provencio is serving fifty years to life in prison for killing her husband in their Temecula home in December of 1998.' She insisted his death was an accident, caused by a gun going off in her hand when she removed it from their bed for safekeeping.2 She and her husband fought the night he died, and their children reported he was crying afterwards, before they went to bed. That night, she shot him in the head while he was sleeping.4 While she told friends shortly before the killing that he was mean to her, Provencio said she could not leave because she did not want to share custody of their children.' Several times over the two years preceding the murder, Provencio told her neighbor that she wanted him * Ryan Newby, Executive Articles Editor, Hastings Women's Law Journal, 2010- 2011, J.D. -

DNA REPLICATION, REPAIR, and RECOMBINATION Figure 5–1 Different Proteins Evolve at Very Different Rates
5 THE MAINTENANCE OF DNA DNA REPLICATION, SEQUENCES DNA REPLICATION MECHANISMS REPAIR, AND THE INITIATION AND COMPLETION OF DNA REPLICATION IN RECOMBINATION CHROMOSOMES DNA REPAIR GENERAL RECOMBINATION SITE-SPECIFIC RECOMBINATION The ability of cells to maintain a high degree of order in a chaotic universe depends upon the accurate duplication of vast quantities of genetic information carried in chemical form as DNA. This process, called DNA replication, must occur before a cell can produce two genetically identical daughter cells. Main- taining order also requires the continued surveillance and repair of this genetic information because DNA inside cells is repeatedly damaged by chemicals and radiation from the environment, as well as by thermal accidents and reactive molecules. In this chapter we describe the protein machines that replicate and repair the cell’s DNA. These machines catalyze some of the most rapid and accu- rate processes that take place within cells, and their mechanisms clearly demon- strate the elegance and efficiency of cellular chemistry. While the short-term survival of a cell can depend on preventing changes in its DNA, the long-term survival of a species requires that DNA sequences be changeable over many generations. Despite the great efforts that cells make to protect their DNA, occasional changes in DNA sequences do occur. Over time, these changes provide the genetic variation upon which selection pressures act during the evolution of organisms. We begin this chapter with a brief discussion of the changes that occur in DNA as it is passed down from generation to generation. Next, we discuss the cellular mechanisms—DNA replication and DNA repair—that are responsible for keeping these changes to a minimum. -

Africans do not want or need Britain's development aid. 7:01AM BST 22 Aug 2010 13 Comments (http://www.telegraph.co.uk/comment/letters/7958485/What-is-the-best-way-to-help-the-worlds- deserving-poor.html#disqus_thread) SIR – The parlous state of the public finances in Britain provides the perfect opportunity for British taxpayers to end their half-century-long experiment with "development aid", which has, since its inception, stunted growth and subsidised bad governance in Africa. As Africans, we urge the generous-spirited British to reconsider an aid programme they can ill afford, and which we do not want or need. A real offer from the British people to help our development would consist of the abolition of the Common Agricultural Policy, which keeps African agricultural exports out of the European marketplace. It is that egregious policy, combined with the weight of regulations, bad laws and stifling bureaucracy, subsidised by five decades of development aid, which prevents Africans from lifting themselves out of poverty. Andrew Mitchell, the Secretary of State for International Development, speaks about a "moral imperative" to combat poverty around the world. We could not agree more. The British have a unique opportunity to cut the deficit and help Africa: please, ask your new government to stop your aid. Andrew Mwenda Editor, Independent -
Review Questions DNA Replication
Review Questions DNA Replication 1. Explain semi-conservative replication. Prior to cell division, a cell must make a copy of its DNA to pass along to the next generation. Copying DNA is called “replication”. Rather than build a DNA molecule from scratch, the new DNA is composed of one old DNA strand (used as the template) and one brand new strand. “Semi-conservative” means that half of the new DNA molecule is old DNA. 2. How can the speed of DNA replication increase while the rate of replication remains constant? The conundrum of DNA replication is that in humans the replication enzymes can copy at a rate of 50 base pairs per second. That may seem like a fast rate but there are 3.1 billion base pairs in the human genome. At that rate, if the machinery started at one end of the DNA and replicated all the way down to the other end, it would take ~ 2 years to copy one DNA molecule. Replication occurs much faster than that. How? Well, the answer is that DNA replication starts at many places along the molecule. These separate “origins of replication” form “replication bubbles”. Once a bubble forms, replication moves in both directions. These expanding bubbles of replication will eventually meet and the whole genome will be copied in a matter of hours rather than years. 3. Explain the process of DNA replication. Unwinding and Unzipping the Double Helix. The two strands in a DNA molecule are connected by hydrogen bonds between the complementary bases. An enzyme called “helicase” travels along the DNA unwinding and breaking the hydrogen bonds between the two strands. -

The Glorification of Lady Diana Spencer
CÉLINE GRÜNHAGEN ‘Our Queen of Hearts’—the Glorification of Lady Diana Spencer A critical appraisal of the glorification of celebrities and new pilgrimage eligiosity and spirituality respectively have always been and will be subject Rto change. The emergence of the manifold forms of new religious and spir- itual movements in the last century includes a variety of cult-like venerations of specific individuals, such as politicians (e.g. Mao, Lenin) and modern idols (e.g. Elvis Presley, Princess Diana, Michael Jackson), who are glorified like saints. Devotees gather annually for memorials of their departed idols or travel long distances to visit the tomb, former home, etc. of a specific person to pay tribute to him or her. Due to the motivations of these devotees, the trouble they take, the practices and the tangible emotionality that are con- nected with this phenomenon, it can be considered a form of pilgrimage. In the following I will present some thoughts about the glorification of celebri- ties which leads to these considerable forms of cult and pilgrimage, using as an example the case of Lady Diana Frances Spencer (d. 1997). The death of a princess Diana Frances Spencer was born on 1 July 1961. Belonging to the high nobil- ity of the United Kingdom, the Spencer family had no material shortcom- ings, but allegedly the divorce of the parents was fought on the backs of the children. Diana was regarded as a very poor student; after school she started working in a kindergarten. In 1981 she married Prince Charles and became Her Royal Highness the Princess of Wales, a title she lost due to the divorce. -

Academic Editor: Peter Frank Received: 31 March 2015 / Accepted: 18 June 2015 / Published: 23 June 2015 Abstract: Higher eukaryotes have three types of DNA ligases: DNA ligase 1 (Lig1), DNA ligase 3 (Lig3) and DNA ligase 4 (Lig4). While Lig1 and Lig4 are present in all eukaryotes from yeast to human, Lig3 appears sporadically in evolution and is uniformly present only in vertebrates. In the classical, textbook view, Lig1 catalyzes Okazaki-fragment ligation at the DNA replication fork and the ligation steps of long-patch base-excision repair (BER), homologous recombination repair (HRR) and nucleotide excision repair (NER). Lig4 is responsible for DNA ligation at DNA double strand breaks (DSBs) by the classical, DNA-PKcs-dependent pathway of non-homologous end joining (C-NHEJ). Lig3 is implicated in a short-patch base excision repair (BER) pathway, in single strand break repair in the nucleus, and in all ligation requirements of the DNA metabolism in mitochondria. In this scenario, Lig1 and Lig4 feature as the major DNA ligases serving the most essential ligation needs of the cell, while Lig3 serves in the cell nucleus only minor repair roles. -
DNA Replication in Prokaryotes
392 Chapter 14 | DNA Structure and Function 14.4 | DNA Replication in Prokaryotes By the end of this section, you will be able to do the following: • Explain the process of DNA replication in prokaryotes • Discuss the role of different enzymes and proteins in supporting this process DNA replication has been well studied in prokaryotes primarily because of the small size of the genome and because of the large variety of mutants that are available. E. coli has 4.6 million base pairs in a single circular chromosome and all of it gets replicated in approximately 42 minutes, starting from a single site along the chromosome and proceeding around the circle in both directions. This means that approximately 1000 nucleotides are added per second. Thus, the process is quite rapid and occurs without many mistakes. DNA replication employs a large number of structural proteins and enzymes, each of which plays a critical role during the process. One of the key players is the enzyme DNA polymerase, also known as DNA pol, which adds nucleotides one-by-one to the growing DNA chain that is complementary to the template strand. The addition of nucleotides requires energy; this energy is obtained from the nucleoside triphosphates ATP, GTP, TTP and CTP. Like ATP, the other NTPs (nucleoside triphosphates) are high-energy molecules that can serve both as the source of DNA nucleotides and the source of energy to drive the polymerization. When the bond between the phosphates is “broken,” the energy released is used to form the phosphodiester bond between the incoming nucleotide and the growing chain.
