Dear Sir or Madam: My name is Asuka Ohsawa, and I am a freelance photo researcher for Jones and Bartlett Publishers, Inc., in Boston, MA. We're currently working on an educational textbook by Dr. Benjamin Lewin titled Essential Genes, 2nd Edition, and the author has requested to use the image that appears on the following website: http://www.cgl.ucsf.edu/chimera/ImageGallery/entries/rnabases/ rnabases.html At your earliest convenience, could you please let me know who owns the copyright to the image in question, and how I can get in touch with him/her? In order for us to publish the image properly, we need to acquire a signature from the author of the image. Your kind assistance in this matter will be much appreciated. Should you have any questions or require additional information, please do not hesitate to contact me. Thank you, and I look forward to hearing from you. Best, Asuka Ohsawa Freelance Photo Researcher Jones and Bartlett Publishers, Inc. Email: asukabunny@gmail.com Phone: 718/349-0393
