基本解釋[生物學]選擇性剪接可變RNA剪接旁路RNA剪接英漢例句雙語例句Alternative splicing of pre-messenger RNA is a key feature of transcriptome expansion in eukaryotic cells, yet its regulation is poorly understood.信使RNA前躰可變剪接是真核細胞轉(zhuǎn)錄的一個主要特點,但其調(diào)控知之甚少。Alternative splicing didn't help either: it could be argued that it represents a case of RNA making itself, then making a bunch of different proteins.選擇性拼接也不肯幫忙:它可以被看作另外一種例外——RNA還能自我複制,然後制造出一攬子形形色色的蛋白質(zhì)。In alternative splicing, microscopic "scissors" in a gene chop the genetic material RNA into bits called "exons" and then reassemble the bits in a different order to form a new RNA molecule.在選擇性剪切中,模板RNA被剪切成不同的片斷稱爲外顯子,然後這些片斷再按不同的順序拼接形成多種新的RNA分子。alternative rna splicing更多例句詞組短語短語RNA alternative splicing 選擇性剪接alternative rna splicing更多詞組專業(yè)釋義生物學選擇性剪接可變RNA剪接旁路RNA剪接
