  • finding promoters using ensembl biomart

    Hi,

    I have found the upstream promoter of length 200 for some genes using Ensembl Biomart. But my supervisor asked me to find 10 promoter of each gene and to find any similarity between them. How can I find 10 promoter for one gene? For example should I just change the length of upstream Flank(gene) section in biomart?
    But then ofcourse they have some exactly common regions.
    Can any one help me how to do this?
    Thank you

    Are you sure the supervisor did not mean 10 promoters for 1 gene but from 10 different organisms? Unless the gene of interest has 10 different TSSs, I do not understand the question unless it means to look for cross-species similarity.

      This is what he has asked : "Take at least 10 gene promoters of the top hits....."
      I also was thinking it can not be meaningful

        What kind of top hits is he referring to? Are these genes from a study that has resulted in a rank ordered list?

        Maybe he wants you to find common motifs (binding sites) in the promoter regions of the top 10 genes from the gene list.

          Strategies for Sequencing Challenging Samples
          by seqadmin


          Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
