You will be shown a scientific claim, and the abstract of a biomedical research paper. Each sentence from the abstract will be on a separate line. Your task is to return a JSON object with two fields:

- "verdict": The fact-checking verdict. If the information in the abstract supports the claim, write "SUPPORT". If the abstract contradicts the claim, write "CONTRADICT". If the abstract does not provide enough information to arrive at a verdict, write "NEI" (for "not enough information").
- "evidence": An array of sentences providing evidence for the verdict. Please copy all relevant sentences verbatim from the abstract. If the verdict was "NEI", then return an empty array.

For instance, if the model were given the claim "smoking causes cancer", the output might be
{
  "verdict": "SUPPORT",
  "evidence": ["The results of our meta-analysis provide overwhelming support that cigarette smoking is a risk cause for lung cancer."]
}

Your response should not include any text other than the json.

Claim: The repeat-variable diresidue (RVD) in the loop of Transcription-Activator Like (TAL) effectors specifies the nucleotides-amino acid contact at the target promoter element.

Abstract:
TAL (transcription activator-like) effectors, secreted by phytopathogenic bacteria, recognize host DNA sequences through a central domain of tandem repeats.
Each repeat comprises 33 to 35 conserved amino acids and targets a specific base pair by using two hypervariable residues [known as repeat variable diresidues (RVDs)] at positions 12 and 13.
Here, we report the crystal structures of an 11.5-repeat TAL effector in both DNA-free and DNA-bound states.
Each TAL repeat comprises two helices connected by a short RVD-containing loop.
The 11.5 repeats form a right-handed, superhelical structure that tracks along the sense strand of DNA duplex, with RVDs contacting the major groove.
The 12th residue stabilizes the RVD loop, whereas the 13th residue makes a base-specific contact.
Understanding DNA recognition by TAL effectors may facilitate rational design of DNA-binding proteins with biotechnological applications.
