In this task, you are given a sentence. You are expected to recognize the name of gene or protein. Although there might be several correct answers, you need to write one of them.

Example Input:  Thus , the potential induction of this gene rearrangement by E1A gene therapy is unlikely to be clinically significant in the treatment of advanced malignant disease .
Example Output: E1A gene

Example Input:  Transcripts appear to be initiated from an upstream promoter , P1 , located in front of the tRNA ( met1 ) gene and from three internal promoters : P2 is located immediately in front of the tRNA ( met2 ) gene ; PL10 is near the beginning of the L1 - L10 intergenic space , and PL12 is at the end of the L10 gene sequence .
Example Output: L10 gene sequence

Example Input:  Nucleotide sequence of the gag gene and gag - pol junction of feline leukemia virus .
Example Output:
gag gene
