Reference Check

If a reference checks out, add the relevant quote, so that your checking can be verified later.

• 1ab, 2 not checked - no access
• 3 ERROR - based on abstract: source gives 22-26 angstrom (2.2 - 2.6 nm) width
• 4 not checked - no access
• 5ab checked OK
  • a quote="The novel feature of the structure is the manner in which the two cheins are held together by the purine and pyrimidine beses. The planes of the bases are perpendicular to the fiber axis. They are joined together in pairs, a single base from one chain being hydrogen-bonded to a single base from the other chain"
  • b quote not applicable
• 6 not checked - no access
• 7ab ERROR
  • 7a ERROR - does not seem a suitable source: supporting information may or may not be inferred but suggest replacement with a source that provides it explicitly
  • 7b ERROR - does not provide structural information of nucleotides not explicitly state that A+G are purines while C+T are pyramidines
• 8ab not checked - no access
• 9 not checked - no access
• 10, 11 in progress
• 12 not checked - no access
• 13 ERROR - based on pubmed abstract: quote="Cro, repressor, and CAP use alpha-helices for many of the contacts between side chains and bases in the major groove" - suggest this is insufficient to make the assertion that "proteins like transcription factors that can bind to specific sequences in double-stranded DNA usually make contacts to the sides of the bases exposed in the major groove" - suggest further scrutiny of entire text.
• 14 checked ok - quote="The situation in nucleic acid systems is somewhat different: from our present model, the analysis of the different contributions seen in Table 2 shows that the components base stacking, hydrogen bonding, and van der Waals terms are the major partners; the relative contributions are 33.4% base stacking, 30.3% van der Waaks, 18.2% hydrogen bonding, 12.1% hydrophobic, and 6.1% electrostatic"

Reference Check Discussion

Should we just correct the article re: Ref 3, and then pass it? I don't have access to the full article but the abstract was in direct contravention of what it says in the article. --Sean T. Smith 07:01, 17 May 2007 (CDT)

I am working on importing the images - currently delayed due to a technical problem. Please bear with me. --Sean T. Smith 15:06, 17 May 2007 (CDT)
