File source problem with File:B-DNA dodecamer (1D28).png
Thank you for uploading File:B-DNA dodecamer (1D28).png. I noticed that the file's description page currently doesn't specify who created the content, so the copyright status is unclear. If you did not create this file yourself, you will need to specify the owner of the copyright. If you obtained it from a website, please add a link to the page from which it was taken, together with a brief restatement of the website's terms of use of its content. If the original copyright holder is a party unaffiliated with the website, that author should also be credited. Please add this information by editing the image description page.

If the necessary information is not added within the next days, the image will be deleted. If the file is already gone, you can still make a request for undeletion and ask for a chance to fix the problem.

Please refer to the image use policy to learn what images you can or cannot upload on Wikipedia. Please also check any other files you have uploaded to make sure they are correctly tagged. Here is a [ list of your uploads]. If you have any questions or are in need of assistance please ask them at the Media copyright questions page. Thank you. Kelly hi! 09:04, 17 May 2016 (UTC)
