[Bioc-sig-seq] Downloading a sequence from the NCBI

[Ivan Gregoretti]

How do I download the GeneBank record AF441733.2?
(Mus musculus clone RP23-225M6 45S pre-ribosomal RNA gene, partial
sequence; and intergenic spacer, partial sequence)

I know that I could manually download it as a fasta file and then read
it into R but there is probably a single step strategy.

I wanted to use biomaRt but since the record seems to be absent from
Ensembl, I can't expect biomaRt to fetch it. Can I?

Thank you,

Ivan
