Cells Hormones Make Brain Bind Mrna's Specific Complementary

en It is possible to make specific complementary DNA's (cDNA's) that can serve as molecular probes to seek out the messenger RNA's (mRNA's) of the peptide hormones. If brain cells are making the hormones, the cells will contain these mRNA's. If the products the brain cells make resemble the hormones but are not identical to them, then the cDNA's should still bind to these mRNA's, but should not bind as tightly as they would to mRNA's for the true hormones.

解释: 与其他难句不同的是,以上的英文不止一句。笔者之所以在本句中不设标志和翻译,是因为这三句话从结构上和意思上来说并不难。然而很少有人能够真正的一次把这段话读清楚,原因在于两个容易混淆的单词cDNA's和mRNA's在文中交替出现,而且相互作用;再加上brain cell和hormones从中捣乱,更难读清楚原文的意思。

原文的主要意思如下:可以用cDNA's来探测mRNA's。如果脑细胞产生了荷尔蒙(hormones),则其中必有mRNA's(意味着可用cDNA's探测荷尔蒙)。如果脑细胞造的不是真荷尔蒙,则可以用cDNA's与其中的mRNA's附着的情况来确定此荷尔蒙的真假。
