identify the following: 1. Characteristics of viruses and why they are not generally considered to be “alive”. * virus= infectious biological particles; 1+ nucleic acid molecules surrounded by protein capsid or envelope * nucleic acid: DNA or RNA, composed of single/double strand (genes encode coat proteins, proteins of regulation of transcription) * capsid: protein coat of virus, viral genome packaging * envelope: lipid bilayer that contains proteins * enveloped

fixated on Truscott as the prime suspect since he was the last person to see Lynne. They didn’t consider any other suspects, even though there was no physical evidence linking him to the murder. He was arrested 24 hours later, and stood trial as an adult. (Steven Truscott | Murderpedia). The entire case was based on circumstantial evidence, and Truscott was found guilty and became the youngest person in Canada to be sentenced to death at the age of 14. The Crown’s theory was that Truscott committed

nitric oxide (a major vasodilator and angiogenesis factor) and polyamines (key regulators of DNA and protein synthesis) may provide a unified explanation for intrauterine growth retardation in response to the 2 extremes of nutritional problems with the same pregnancy outcome. There is growing evidence that maternal nutritional status can alter the epigenetic state (stable alterations of gene expression through DNA methylation and histone modifications) of the fetal genome. This may provide a molecular

a scene, collecting evidence, and reporting their findings. The essential steps for any investigations team to follow are: Determine team composition, control contamination, document the scene, prioritize evidence collection, and collect, preserve, inventory, package, and transport and submit evidence. After all of that is accomplished the team has to get together to debrief about the crime scene, perform the final survey of the scene and document it. From there the evidence is processed, lab tests

repetitive DNA sequences at the ends of chromosomes which act as protective caps” (Rehman, 2014). When cells divide during mitosis, the chromosomes duplicate in order to ensure that both “daughter” cells receive the same amount of DNA. The telomeres protect the chromosomes during this process to ensure the integrity of the DNA. Telomeres do an excellent job of helping to secure our genetic material, unfortunately they don’t last forever. According to Scientific American, “During the DNA replication

Dr. Alec John Jeffreys is a British geneticist who developed techniques for DNA fingerprinting and DNA profiling that are now used worldwide by investigators to bring justice to perpetrators as well as to resolve paternity and immigration disputes. Jeffreys was born into a middle-class family in Oxford, where he spent the first six years of his life until 1956, when the family moved to Luton, Bedfordshire. He attributes his curiosity and inventiveness to having been gained from his father, as well

Biff Eddington Anthropology 4467 24 April 2011 What is life history theory? What is a primate life history pattern? What is the relationship between brain size and life history? Life history theory is a branch of biology that analyzes the selective forces that have managed the evolution of the schedule and duration of key events in an organism’s lifetime related to investments in growth, reproduction, and survivorship (Bogin, O’Rourke and Stinson 547). The reason that there are differences

Are Imprinted Genes Adaptive or Maladaptive? Epigenetics is referred to be the study of heritable changes other than those in the DNA sequence that encompass two major modifications of DNA or chromatin: DNA Methylation, the covalent modifications of cytosine, and post-translation modification of histones including methylation that is a highly intricate process that occurs within each cell as well as supplying fluid in the brain and within the liver, acetylation , phosphorylation and sumoylation
