Given the task definition and input, reply with output. In this task, you're given a paragraph and title from the research paper. Your task is to classify whether the given title is suitable or not for the research paper based on the given paragraph. Return "True" if title is proper according to paragraph else "False".

Paragraph: Proteolytic processing of the mouse hepatitis virus strain A59 (MHV-A59) replicase gene product, pp1a, results in polypeptides p28, p65, p50, and p240 in infected cells. Based on previously identi ed p28 and p65 cleavage sites, a p50 cleavage site was proposed to occur between Ala-1262 and Ala-1263. Results of mutagenesis and in vitro cleavage assays show that PLP-1 was able to cleave in trans when the proposed p50 cleavage sequence replaced the p28 cleavage sequence. Mutagenesis was also used to investigate cleavage between Gly-904 and Val-905, a cleavage site predicted to produce a precursor of p65, p72, that was detected in cells infected with MHV strain JHM, but not with MHV-A59. No cleavage could be detected using substrate that carried both the p65 site and the predicted p72 cleavage sequence. Thus, it appeared that PLP-1 could recognize the proposed p50 sequence but not the predicted p72 site under the in vitro conditions used.
