    Sammanfattning : Highly sensitive biosensors were developed for environmental and medical applications. The biosensors were based on bioengineered proteins as biorecognition elements coupled to a highly sensitive capacitive transducer. LÄS MER

  3. 2. Orientational dynamics of single molecules applied to protein-DNA target search

    Författare :Emil Marklund; Johan Elf; Erwin Peterman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single molecule imaging; fluorescence correlation spectroscopy; gene regulation; transcription factor; lac operon;

    Sammanfattning : Cells in all life forms regulate their genes with the help of transcription factors (TFs). These proteins turn genes on or off by binding regulatory motifs present in the DNA. Before this binding can occur, a TF needs to search and find the specific binding site in the genome of the cell. LÄS MER

  4. 3. Splice site selection in Saccharomyces cerevisiae pre-mRNA splicing

    Författare :B G Mattias Luukkonen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pre-mRNA splicing is the process by which intervening sequences (introns) are removed from the coding sequences (exons) resulting in a mature messenger-RNA (mRNA). Splicing takes place in a large ribonucleoprotein complex termed the spliceosome, composed of several protein components and the five small nuclear RNAs (snRNAs) U I, U2, U4, U5 and U6. LÄS MER
