Gene Query http://www.ncbi.nlm.nih.gov/ HBB gene for homo sapiens
Our query will give the following results Sequences available Proteins available Expression data, available from several high-throughput transcriptome technologies. Micorarray Experiment
Sequences available We check for sequences
Info concerning the GENE Info concerning the HBB Nucleotide Sequence
Info concerning the GENE Info concerning the HBB Nucleotide Sequence Lets check the nucleotide sequence by opening the link
Info for the sequence Accession from RefSeq DB Latest annotation Length “vesrion” and “gi” accessions: CHECK LINK FOR INFO: http://www.ncbi.nlm.nih.gov/Sitemap/sequenceIDs.html
Lower part of the previous file Additional links
More choices of visualizing the sequence and the related information
More choices of visualizing the sequence and the related information Lets choose the coding region (CDS). This will give the minimum information concerning Gene and CDS (see next slide)
Start end of GENE Start end of coding region Link to other databases
Lets extract the coding sequence by clicking at the CDS link
It opens the part concerning the cds Check the different (lower) length to that of the gene Upper part of the file Lower part of the file terminates with the coding sequence HOW TO EXTRACT
Above we have the option to choose the format. Since we want to extract the Coding sequence, we choose FASTA format.
WE SAVE THE NUCLEOTIDE SEQUENCE OF HBB. WE MAY NOW OPEN AND VISUALIZE THE SAVED SEQUENCE USING A TEXT EDITOR
LETS GO BACK TO THE INITIAL QUERY Info concerning the GENE Info concerning the HBB Nucleotide Sequence Lets check the GENE INFORMATION
GENE STRUCTURE Plus Genomic info
Info for the 5’ and 3’ UTR, introns and exons. Information for position on GENOME
