外显子

It appears to confirm that morphologically and genetically distinct X and Y chromosomes evolved from an identical pair, a pair of autosomes, and ZFX may be exons and play certain role in the mammal sex determination.

这不仅说明X和Y染色体可能起源于同一对染色体。而且也提示ZFY和ZFX可能是外显子，即具有转录功能，并且在哺乳类的性别决定中具有一定的作用。

An expression construct specified in mammary gland with double cistrons of human G-CSF gene and IRES-EGFP gene under control of ovine beta-lactoglobulin gene flanking sequence,has been constructed in two parts (named fragment I and Fragemnt II)that share an overlapping region of 2.2 kb sequence.Two sites of loxp and lox2272 for homologous recombination were inserted into both flanking regions of G-CSF.The lengths of fragment I and Fragment II are 5.9kb and 5.6 kb,respectively.The whole length of the expression vector (β-LG-hG-CSF-IRES-EGFP) is 9.3 kb.
