Popular Abstract in Swedish Introduktion till nukleotider Nukleotider är viktiga byggstenar för DNA och RNA. Det finns två typer av nukleotider, puriner och pyrimidiner. Nukleotider kan även fungera som signalmolekyler inom eller mellan celler. Dessutom kan många encelliga mikroorganismer, så som jäst och bakterier, använda dem som kvävekälla, genom att bryta ner dem och utvinna kvävet, som sedan Pyrimidines are important precursors for nucleic acids, and constantly synthesized and degraded in the cell to maintain a balanced supply. Many microoganisms can also extract the nitrogens from the pyrimidine ring, and use them as a nitrogen source when “preferred” sources are absent. Four different pathways, by which pyrimidines can be degraded, are known. I have studied the last discovered, but

Hereditary Nonpolyposis Colorectal Cancer (HNPCC) is one of our most common hereditary cancer syndromes and confers an increased risk for several tumor types, with the greatest lifetime risks being for colorectal cancer and endometrial cancer. Hereditary mutations in one of several mismatch-repair (MMR) genes cause the syndrome, and 39 such mutations, involving the genes MLH1, MSH2 and MSH6, have

Populärvetenskaplig sammanfattning Inom vissa delar av den kemiska industrin, exempelvis läkemedelsindustrin, är det viktigt att kunna de-signa och skräddarsy organiska molekyler så att de har precis den strukturen man eftersträvar. Till sin hjälp finns det en mängd olika organiska reaktioner som kan användas för att koppla ihop och bygga molekyler på olika sätt. En molekyl med en optimerad strukt

This essay examines the Bavarian physician, mining engineer, and Catholic romantic philosopher Franz von Baader's (1765-1841) enigmatic claim that we think because we are thought with the help of the moral theologian Servain Pinckaers OP (1925-2008) and the psychologist Mihaly Csikszentmihalyi (1934-2021). Using Pinckaers' idea of 'fontal knowledge' and Csikszentmihalyi's notion of flow, I interprThis essay examines the Bavarian physician, mining engineer, and Catholic romantic philosopher Franz von Baader's (1765-1841) enigmatic claim that we think because we are thought with the help of the moral theologian Servain Pinckaers OP (1925-2008) and the psychologist Mihaly Csikszentmihalyi (1934-2021).

The purpose of this dissertation is to explore the heritagisation of Swedish sports, which is examined through studies of five Swedish sports museums of today. Additionally, the disseration explores the heritagisation of Swedish sports in a wider historical perspective, mainly focusing on the years between 1900 and 2000.There are plenty of sports museums in Sweden today, most of them run by amateu
