I have ref_seq proteins, i wanted its DNA sequence from NCBI how can it get using proteins ref_seq ids?
Use the UCSC table browser to get the sequence for your ID(s).
Thanks for helping me . But i did'nt find option for plants at UCSC. I have plant refseq proteome data and i want DNA seq data of respective protein ids.
That's because there are no plants in UCSC. :) Next time, try to be more precise with your question... that safes some time.
With plants, I cannot help you. At least not in a simple way.
