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

2. Ribosomal RNA Modification Enzymes : Structural and functional studies of two methyltransferases for 23S rRNA modification in Escherichia coli
Abstract : Escherichia coli ribosomal RNA (rRNA) is post-transcriptionally modified by site-specific enzymes. The role of most modifications is not known and little is known about how these enzymes recognize their target substrates. READ MORE

3. Exotic Ribosomal Enzymology
Abstract : This thesis clarifies intriguing enzymology of the ribosome, the multiRNA/multiprotein complex that catalyzes protein synthesis (translation). The large ribosomal RNAs (23S and 16S rRNAs in E. coli) are post-transcriptionally modified by many specific modification enzymes, yet the functions of the modifications remain enigmatic. READ MORE

4. Accessory factors for ribosomal assembly
Abstract : The assembly of ribosomal RNA (rRNA) and ribosomal proteins (r-proteins) into ribosomal subunits (30S and 50S) is a complex process. Transcription of rRNA requires antitermination proteins and the primary transcripts are processed by ribonucleases. READ MORE

5. Ribosomal translocation in real time : Method development to Applications
Abstract : Translational elongation is the process in which the ribosome adds one amino acid at a time to the nascent peptide chain. As the ribosome elongates the peptide chain by 14 - 20 amino acids per second and performs hundreds of such cycles per protein, ‘elongation’ is one of the most crucial steps in translation. READ MORE
