求下面一句英文的结构分析.
“ Most of these genes were identified through their homology with known RNA interference components in animals,a candidate-gene approach,mutants with developmental phenotypes resembling those of mutants deficient in miRNA biogenesis or with elevated levels of miRNA target genes,and forward genetic screening using a GFP sensor targeted by endogenous miRNA .”
“ Most of these genes were identified through their homology with known RNA interference components in animals,a candidate-gene approach,mutants with developmental phenotypes resembling those of mutants deficient in miRNA biogenesis or with elevated levels of miRNA target genes,and forward genetic screening using a GFP sensor targeted by endogenous miRNA .”
【Most of these genes】 主语 【were identified】 谓语【through their homology】状语 with known RNA interference components in animals,（主干：包含短语 identify……with……）
【a candidate-gene approach】,（是上面一个句子的同位语）{【mutants with developmental phenotypes resembling those of mutants deficient in miRNA biogenesis or with elevated levels of miRNA target genes】,and 【forward genetic screening using a GFP sensor targeted by endogenous miRNA】 .”}整个是对a candidate-gene approach进一步的解释；而中间则是由and连接的2个并列句；第一个句子中是由or连接的并列句.
