ARSA (All-Round Retrieval of Sequence and Annotation):  
ARSA is a cross database search engine used for sequence retrieval from multiple 
databases (http://arsa.ddbj.nig.ac.jp/html/). In it any combination of features from the flat 
file format of an entry can be used as query for retrieval. Since its launch in 2004, there has 
been continuous upgradation of ARSA. Due to its frequent usage it has replaced SRS 
(Sequence Retrieval System) tool, which was earlier available at DDBJ for data retrieval by 
use of key words. NCBI also has a cross-database search and retrieval tool called as Entrez 
while EMBL has SRS with similar function. 
ARSA has two types of search options: 
? Quick Search: It involves typing a single or combination of key words in the search 
window . It is fast as compared to advanced search.

? Advanced Search: Advanced search is a detailed search option, which involves 
searching with help of number of parameters. Although it is more time consuming 
but it gives very accurate results. Figure 1.3 shows the advanced search page of 
ARSA. Various parameters which can be used in advanced search include gene 
name, accession number, division, sequence length, molecule type, author name etc.

TXSearch (Taxonomy Search):  
Taxonomy search is a retrieval tool for Taxonomy database (integrated by DDBJ, GenBank 
and EMBL) and aim of this tool is to amalgamate organism names 
(http://txsearch.ddbj.nig.ac.jp/top-e.html). It is used for searching unified taxonomy 
names. This information is required during submission of nucleotide sequence where 
complete taxonomic classification of the organism is needed. The search can be done by 
using Taxonomic name, ID, class or rank. Taxonomic classification of Brassica juncea 
retrieved using TXSearch is shown in Figure.

Vector Screening System (VSS):  
In Recombinant DNA technology (for cloning, over-expression or transformation), PCR 
amplified genomic DNA or complementary DNA (cDNA) is inserted into a vector. During 
sequencing, the sequence of the cloned DNA (genomic or cDNA) segment usually gets 
contaminated by the vector sequence. Therefore it becomes necessary to recognize and 
remove vector sequence from the DNA sequence otherwise it may lead to wrong conclusion 
about the results obtained. 
Vector Screening system (http://vector.ddbj.nig.ac.jp/top-e.html ) as the name suggests is 
used for detection of vector sequence contamination in the query sequence. It uses a target
