Overview:

Analyses of RNA data that focus on its structure and evolution

Quick Navigation:


Explanation of Content:

2A. RNA Structure

Analyses that relate RNA sequence patterns to structure.

Nucleotide Frequency Data

Tables that contain the types of nucleotides and their frequencies for each position in the RNA molecule.

Nucleotide Modification

Descriptions of modified nucleotides that are known to appear in RNA.

RNA2DMap

Interactive comparative data presentation, using secondary structure as a scaffold.

Crystal Structure Information

Analyses of RNA crystal structures in the context of the corresponding comparative structure models.

2B. Evolution of RNA

Analyses that reveal patterns of variation and conservation in sets of RNA sequences.

RNA Conservation Diagrams

Secondary structure diagrams that reveal the most conserved nucleotide at each position that is present in the vast majority of the sequences.

RNA Signatures

Sequence- and structure-level features that distinguish one group of organisms from other groups.

RNA Microheterogeneity

Secondary structure diagrams that show the nucleotide variation present within the sequenced members of a single species.

2C. Introns

Two distinct presentations of intron data.

rRNA Introns

Four preconfigured online tables that disseminate intron information (for the introns that occur in the 16S and 23S rRNAs) and emphasize the major dimensions inherent in this data: 1) intron position in the rRNA, 2) intron type, 3) phylogenetic distribution, and 4) number of introns per exon gene.

Group I/II Intron Distributions

Three tables which compare intron types, phylogeny, exon, and cell location for group I and II introns and all other introns that occur in the ribosomal RNAs.

2D. Structural Statistics

Provides information about different quantitative characteristics of the comparative structures.

2E. Folding

Folds a submitted RNA sequence into its secondary structure.

2F. Alignment

Aligns submitted RNA sequences against a template alignment.
