1. Perception of risk : studies of risk attitudes, perceptions and definitions
Sammanfattning : .... LÄS MER
2. Metal ion cooperativity in Escherichia coli RNase P RNA
Sammanfattning : RNase P is an essential ribonuclease responsible for removal of the 5’ leader of tRNA precursors. Bacterial RNase P consists of an RNA subunit and a small basic protein. The catalytic activity is associated with the RNA subunit, i.e. LÄS MER
3. Quaternary structure and interaction approaches to allosteric regulation of class I ribonucleotide reductases
Sammanfattning : Deoxyribonucleic acid (DNA) chains in which our genetic blueprint is stored are built from four DNA precursors by DNA polymerases. The enzyme ribonucleotide reductase (RNR) provides the only de novo synthesis pathway of deoxyribonucleotides from ribonucleotides and is essential for nearly all organisms. LÄS MER
4. Fysik, lärande samtal och genus. : En studie av gymnasieelevers gruppdiskussioner i fysik
Sammanfattning : This thesis investigates how students in upper secondary school solve problems and discuss physics in small groups. The study examines how gender, knowledge in physics and the image of the subject physics are constructed in the students’ conversation and how these processes are related to each other. LÄS MER
5. The deep evolutionary roots of non-coding RNA - a comparative genomics approach
Sammanfattning : Non-coding RNAs (ncRNA) are a diverse group of genes that do not encode proteins but function exclusively on the level of RNA and were originally suggested to be remnants of a pre-DNA stage of life known as the RNA world. More recent work, however, has uncovered a rich repertoire of previously unknown families with possible consequences for our understanding of the origin and evolution of the modern RNA infrastructure.
