一、生殖生物学中重要的新发现卵清蛋白基因的结构:PRB证实了小鸡卵清蛋白基因的基本结构,首先发现了天然卵清蛋白基因克隆,并完成了全部卵清蛋白基因的序列分析以及基因成熟RNA转录。发现这是由7个不同长度的插入序列分离成8个段,天然的卵清蛋白基因的硷基对在7,000以上,而其成熟的RNA信息(mRNA)却仅有1,859硷基对,这种明显的差异主要是由于DNA插入序列在成熟过程mRNA转录缺损所致。这是关于受生殖激素调节的高等动物天然基因结构研究的初步报告,在生 First, the important findings in reproductive biology Ovalbumin gene structure: PRB confirmed the basic structure of the chicken egg ovalbumin gene, first discovered the natural egg albumin gene cloning, and completed all the ovalbumin gene sequence Analysis and Gene Mature RNA Transcription. This was found to be separated into 8 segments by 7 different length insertions. The native ovalbumin gene has over 7,000 base pairs, whereas its mature RNA message (mRNA) has only 1,859 base pairs. The obvious difference was mainly due to the transcriptional defect of DNA during the maturation of DNA insertions. This is a preliminary report on the natural genetic structure of higher animals regulated by reproductive hormones.
