To gain further insight into the molecular mechanisms that control tal-1 expression , we investigated tal-1 chromatin structure in erythroid/megakaryocytic cell lines and in T-cell lines either with or without tal-1 rearrangements .
 DNA: tal-1; DNA: tal-1 chromatin structure; cell line: T-cell lines; DNA: tal-1; DNA: tal-1 rearrangements; DNA: tal-1; cell line: erythroid/megakaryocytic cell lines
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2". 
Option: cell line, protein, RNA, DNA, cell type
