  1. 1. Ribosome and ribosomal RNA Structure : An experimental and computational analysis of expansion segments in eukaryotic ribosomal RNA

    Författare :Gunnar Alkemar; Odd Nygård; Anders Virtanen; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eukaryotes; expansion segment; ribosomes; rRNA; secondary structure; structure of rRNA.; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

    Sammanfattning : Ribosomes are large ribonucleoprotein complexes which incorporate amino acids into peptide chains during translational process in all types of living cells. The eukaryotic ribosome is larger compared to its prokaryotic counterpart. LÄS MER

  2. 2. A Study in RNA Bioinformatics : Identification, Prediction and Analysis

    Författare :Eva Freyhult; David Ardell; Robert Giegerich; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNA; bioinformatics; secondary structure; structure prediction; dynamic programming; energy landscape; homology search; sequence logo; tRNA; Bioinformatics; Bioinformatik;

    Sammanfattning : Research in the last few decades has revealed the great capacity of the RNA molecule. RNA, which previously was assumed to play a main role only as an intermediate in the translation of genes to proteins, is today known to play many important roles in the cell in addition to that as a messenger RNA and transfer RNA, including the ability to catalyze reactions and gene regulations at various levels.

  3. 3. Non-protein-coding RNA : Transcription and regulation of ribosomal RNA

    Författare :Stefanie Böhm; Ann-Kristin Östlund Farrants; Brian McStay; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ribosomal RNA; non-coding RNA; ribosomal genes; rDNA gene; B-WICH; chromatin remodelling; histone modification; Cell Biology; cellbiologi;

    Sammanfattning : Cell growth and proliferation are processes in the cell that must be tightly regulated. Transcription of ribosomal RNA and ribosomal biogenesis are directly linked to cell growth and proliferation, since the ribosomal RNA encodes for the majority of transcription in a cell and ribosomal biogenesis influences directly the number of proteins that are synthesized.

  4. 4. Lead(II) as a Tool for Probing RNA Structure in vivo

    Författare :Magnus Lindell; Gerhart Wagner; Roland Hartmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; lead II cleavage; RNA structure; in vivo probing; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Sammanfattning : Chemical modification and limited enzymatic hydrolysis are powerful methods to obtain detailed information on the structure and dynamics of RNAs in solution. In the work presented here I have taken advantage of the properties of the divalent metal ion lead(II) to establish it as a new probe for investigating the structure of RNA in vivo. LÄS MER
