哺乳动物

Based on the conservation of miRNAs sequence, we compared the known miRNAs among five mam-mals, i.e., human, mouse, cattle, pig and dog with the sequence of sheep genome that is highly homologous to goat genome, published on the NCBI, and 11 candidate miRNAs were eventually obtained. RT-PCR analysis showed the expression of the 11 miRNAs in brain and 5 in liver, indicating that they might be novel miRNAs. The methodology provides an alternative approach to the exploration of new miRNAs in goat.

根据miRNA分子具有一定的保守性，文章将人、小鼠、牛、猪和狗5种哺乳动物已知的miRNA分子与NCBI公布的与山羊具有极高同源性的绵羊基因组序列对比，获得11条miRNA候选分子，然后通过逆转录聚合酶链反应验证，发现在山羊脑组织中这11条分子均有表达，肝脏组织中有5条分子表达，初步确定为山羊新的miRNA分子，为寻找山羊miRNA提供了新的思路。

Whereas a lot of nov mRNA positive neurons were widely localized in the brain of mammals—cattle, dog and cat, strong positive signal was found in pons, cerebellum, thalamus, hypothalamus and cerebrum of these species.

哺乳动物牛、犬和猫脑中nov mRNA阳性神经元广泛分布，在脑干、小脑、间脑和大脑都检测到强烈阳性信号。

We found potential evidence of a severe population bottleneck in the cave lion during the previous interstadial, sometime after 48 000 years, adding to evidence from bison, mammoths, horses and brown bears that megafaunal populations underwent major genetic alterations throughout the last interstadial, potentially presaging the processes involved in the subsequent end-Pleistocene mass extinctions.

这些生活在不列颠群岛以及欧洲和北美地区的狮子的生存环境与目前非洲的大型猫科动物完全不同：在更新世，英国是苔原冻土地带，就像现在的俄罗斯草原一样，很多大型动物聚集那里，如哺乳动物、羊毛犀牛、巨型鹿等。13000年前，这些狮子和大型食草动物在大灭绝中消失。

Many of the later mammals,though now extinct,were known to primitive man and were featured by him in cave painting and on bone carvings.

尽管许多后来出现的哺乳动物已经灭绝，但它们却为原始人所熟知，并将它们画在洞穴的墙壁上或刻在骨头上。

Cecil: And this, of course, is the Hall of African Mammals.

这个，当然就是非洲哺乳动物展示大厅了。

The newest era is called Cenozoic beginning at 65 million years ago. It is the age of Mammals.

最新的一个代叫做新生代，它是从距今6500万年的时候开始的，这个时期是哺乳动物的时代。

The newest era is called Cenozoic beginning at 65 million years ago.

最新的一个代叫做新生代，它是从距今6500万年的时候开始的，这个时期是哺乳动物的时代。

Because the Cenozoic saw the expansion of warm-blooded creatures like ourselves, it is also termed the age of mammals.

因为新生代出现大量的像我们人类一样的热血动物，所以这个时代也称为哺乳动物时代。

Because the Cenozoic saw the expansion of warm-blooded creatures like ourselves, it is also termed the age of mammal s.

因为新生代出现大量的像我们人类一样的热血动物，所以这个时代也称为哺乳动物时代。

Virtually every mammal living in the wild harbors at least one nematode species and one cestode species.

事实上每个野生哺乳动物都寄生有至少一种线虫

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
