It provides a fully integrated, visually-advanced toolset for: sequence alignment and phylogenetics; sequence analysis including BLAST; protein structure viewing, NCBI, EMBL, Pubmed auto-find & much more ...

Genome2D - is for the visualization of transcriptome and other customized data sets (visualizes a bacterial genome with all relevant information such as gene orientation, operon structure, transcriptional terminators or regulator binding sites) on linear chromosome maps constructed from annotated bacterial genome sequences. For a complete list of what this incredible program will do see here. Images and data tables from Genome2D can easily be exported for further use in other presentation programs. (Reference: Baerends, R.J.S.,et al. (2004) Genome Biology, 5: R37).

EMBOSS (European Molecular Biology Open Source Software Suite) can be downloaded from here.

PHIRE - this Visual Basic program performs an algorithmic string-based search on bacteriophage genome sequences, discovering and extracting blocks displaying sequence similarity, corresponding to conserved regulatory elements contained within these genomes in a systematic manner, without any prior experimental or predictive knowledge. (Reference: Lavigne, R. et al. 2004. PHIRE, a deterministic approach to reveal regulatory elements in bacteriophage genomes. Bioinformatics 20: 629-635).

MB DNA Analysis (Oleg Simakov) - MB is a free multi-functional DNA/protein analysis program. It's main advantage is that it combines all of the most widely used features needed for an advanced molecular analysis of genomic/proteomic data. Features of MB include a fast restriction analysis algorithm (included plasmid / linear DNA drawing), promoter analysis, calculation of molecular weights and chemical properties of proteins, prediction of the secondary protein structures (after Chou-Fasman). Protein analysis also includes sequence translation and codon usage table calculation. Other features: hierarchical multiple sequence alignment tool (with a feature to compare secondary structure of proteins), phylogenetic tree building, dot plot, estimation of isoelectric point for proteins, primer design. A tool for the structural analysis of alpha helices is also included in the main package.

GenePalette allows genome sequence visualization and navigation. Users can download from NCBI’s GenBank database large or small segments of genome sequence from a variety of organisms preserving the gene annotation that is associated with that sequence. Sequence elements of interest (transcription factor binding sites, etc. can be searched for and identified in the loaded sequence, and then clearly visualized within a colorful graphical representation of gene organization.

UniPro DPview:- (UniPro Bioinformatics Group, Russia) - this is a tool for finding and analyzing matches between genomes. The user can examine the matches, selecting them directly on the dotplot matrix. This program also allows one to build local alignments with specified parameters (match cost, mismatch and gap penalties), using a modification of the classic Smith-Waterman algorithm. It is possible to find not only the best alignment score-wise, but also so-called "suboptimal" ones which have slightly lesser scores.

Artemis a DNA sequence viewer and annotation tool (Sanger Centre)

SEQtools is a program package for routine handling and analysis of DNA and protein sequences. The package includes general facilities for sequence and contig editing, restriction enzyme mapping, translation, and repeat identification.

Zhang (2003). Nucleic Acids Res. 31: 1780-1789). I have experience some problems in downloading their E. coli genome sequence for analysis and have attached a new version.

DNA for Windows is a compact, easy to use DNA analysis program, ideal for small-scale sequencing projects.

RNAdraw: is an integrated program for RNA secondary structure calculation and analysis by Ole Matzura & Anders Wennborg (1996) Computer Applications in the Biosciences (CABIOS) 12: 247-249

RNAstructure - RNA Secondary Structure Prediction and Analysis for Microsoft Windows. This program includes a secondary structure prediction algorithm, a sequence editor, an integrated drawing tool, the OligoWalk program, OligoScreen, Dynalign, and a partition function calculator. (Reference: D.H. Mathews (2005) Bioinformatics 21: 2246 - 2253.)

loopDloop is a tool for drawing RNA secondary structures in molecular biology.

Chromas will display and prints chromatogram files from ABI automated DNA sequencers, and Staden SCF files which the analysis programs for ALF, Li-Cor and Visible Genetics OpenGene sequencers can create. N.B. only the older versions of the software are free.

FinchTV - Another useful tool for viewing and editing electropherograms.

G-language Genome Analysis Environment provides a greater variety of useful genome analysis tools compared to most existing analysis software packages, and is also easily pluggable. All of its tools are accessible as Perl modules. To get started download genome files from GenBank in *.gbk format (GenBank flat file format).

WinGene - Used to give the reverse complement a given sequence, translate the sequence in all reading frames and identify ORFs (Export polypeptides encoded by a given ORF into WinPep), perform a oligomer analysis (base composition and melting temperature), and perform a restriction analysis.

GeneDoc is a full featured multiple sequence alignment editor, analyzer and shading utility for Windows.

Ridom TraceEdit - displays chromatogram files from Applied Biosystems automated sequencers and files in the Staden SCF format. Incorrect base calls can be edited and saved. (Reference: J. Rothgänger et al. 2006. Bioinformatics 22: 493-494).

DNA Master - is "perhaps the world's greatest sequence editor" and analysis package. Find under "computer."

GeSTer (V. Nagaraja, Indian Institute of Science, Bangalore. India) - is extremely useful in locating stem-loop structures, including rho-independent terminators in annotated genomes. Since it does not run conveniently on Windows XP see how you can modify the *.gbk file so that it works.

RepeatAround - is designed to find “direct repeats”, “inverted repeats”, “mirror repeats” and “complementary repeats”, from 3 bp to 64 bp length, in circular genomes. It processes input files directly extracted from GenBank database and several genomes can be input simultaneously. The program provides visualisation of the repeats location in the genomic structure and the search for specific motifs is also possible. Outputs can be obtained in a spreadsheet containing information on the number and location of the repeats. The software also generates random circular genomes, for statistical evaluations or comparisons between observed and expected repeats distributions.

Staden Package - consists of a series of tools for DNA sequence preparation (pregap4), assembly (gap4), editing (gap4) and DNA/protein sequence analysis (spin). The package was originally developed at the MRC-LMB in Cambridge. It is now open source (BSD licence) and is hosted on sourceforge.net.

It features both circular and linear DNA, user defined restriction sites, genes and multiple cloning site. In addition you can manipulate plasmid by inserting and deleting fragments. Created drawings can be copied to clipboard or saved to disk for later use. Printing from within the program is also supported.

BVTech Plasmid - with this program you can draw circular or linear plasmid map with double strands or single strand. You can label the plasmid with genes and restriction sites in different colors, text, and styles.

History of Selaginella bryopteris


"The application of computational and statistical techniques to biological data processing and analysis, particularly in genomics"

In Hindu mythology, Sanjeevani is a magical herb which has the power to cure any malady. It is believed that medicines prepared from this herb can even revive a dead person. This herb is mentioned in the Ramayana when, during the battle with Ravana, Lakshmana was wounded and was nearly killed by Ravana's son Indrajit. Hanuman was called upon to fetch this herb from the mountDronagiri in the Himalayas. Upon reaching mount Sumeru, Hanuman was unable to identify the herb and decided to lift the entire mountain and brought it to the battle-field.

Novel era of Biosciences the application such as Bioinformatics,Genomics,Proteomics work as Snjeevani for mankind.The Approach of Drug Development is now diverted on Insilico Based Analysis .
