There is a very high volume of traffic coming from your site (IP address 34.236.191.104) as of Sun Oct 24 10:14:34 2021 (California time). So that other users get a fair share of our bandwidth, we are putting in a delay of 11.2 seconds before we service your request. This delay will slowly decrease over a half hour as activity returns to normal. This high volume of traffic is likely due to program-driven rather than interactive access, or the submission of queries on a large number of sequences. If you are making large batch queries, please write to our genome@soe.ucsc.edu public mailing list and inquire about more efficient ways to access our data. If you are sharing an IP address with someone who is submitting large batch queries, we apologize for the inconvenience. To use the genome browser functionality from a Unix command line, please read <a href='http://genome.ucsc.edu/FAQ/FAQdownloads.html#download36'>our FAQ</a> on this topic.

Get DNA for

Position

Note: This page retrieves genomic DNA for a single region. If you would prefer to get DNA for many items in a particular track, or get DNA with formatting options based on gene structure (introns, exons, UTRs, etc.), try using the Table Browser with the "sequence" output format. You can also use the REST API with the /getData/sequence endpoint function to extract sequence data with coordinates.

Sequence Retrieval Region Options:

Add extra bases upstream (5') and extra downstream (3')

Note: if a feature is close to the beginning or end of a chromosome and upstream/downstream bases are added, they may be truncated in order to avoid extending past the edge of the chromosome.

Sequence Formatting Options:

All upper case.
All lower case.
Mask repeats: to lower case to N
Reverse complement (get '-' strand sequence)

Note: The "Mask repeats" option applies only to "get DNA", not to "extended case/color options".
