文本1:
Researchers at the University of California, San Diego, have
discovered the basis for a new type of genetic disorder that
causes severe br本人n abnormalities and might be mistaken for
cerebral palsy. The disorder, which they called Ogden syndrome,
causes global developmental delays that are evident from the
time a child is born, and could be seen on br本人n imaging
studies. The findings, published Jan. 13 in the American Journal
of Human Genetics, are the first to link the gene NAA10 to
human disease.
Researchers found that the NAA10 gene is crucial for the
activity of an enzyme that plays a crucial role in modifying
proteins. When NAA10 is disrupted, the enzyme malfunctions
causing an array of severe symptoms, including delayed
development, speech impediments, muscle stiffness, and, in the
most severe cases, death before the age of 3.
科学家的成就英语作文
英文回答:
The scientific community has witnessed numerous
remarkable achievements that have profoundly impacted our
understanding of the world and transformed our lives. These
groundbreaking discoveries have paved the way for
advancements in various fields, pushing the boundaries of
human knowledge and shaping the course of civilization.
One of the most significant scientific achievements was
the development of the theory of evolution by Charles
Darwin. This groundbreaking work revolutionized our
understanding of the diversity of life on Earth and
provided a comprehensive explanation for the origin and
evolution of species. Darwin's theory has had a profound
impact on fields such as biology, genetics, and ecology,
and continues to shape our understanding of the natural
world.
Another notable achievement was the discovery of the
Lesson One(4学时)
细胞质:动力工厂
生命的大部分特征表现在细胞质的特征上。细胞质大部分由半流体物质组成,并由细胞膜(原生质膜)包被。细胞器悬浮在其中,并由丝状的细胞骨架支撑。细胞质中溶解了大量的营养物质,离子,可溶蛋白以及维持细胞生理需求的其它物质。
The Nucleus: Information Central(细胞核:信息中心)
真核细胞的细胞核是最大的细胞器,细胞核对染色体组有保护作用(原核细胞的遗传物质存在于拟核中)。细胞核含有一或二个核仁,核仁促进细胞分裂。核膜贯穿许多小孔,小分子可以自由通过核膜,而象mRNA和核糖体等大分子必须通过核孔运输。
Organelles: Specialized Work Units(细胞器:特殊的功能单位)所有的真核细胞都含有多种细胞器,每个细胞器都有其特定功能。本节主要介绍核糖体,内质网,高尔基体系,液泡,溶酶体,线粒体和植物细胞中的质体。
核糖体的数量变化从几百到几千,核糖体是氨基酸组装成蛋白质的重要场所。完整的核糖体由大亚基和小亚基组成。核糖体沿着mRNA移动并阅读遗传密码,翻译成蛋白质。一条mRNA上可能有多个核糖体,称多聚核糖体。大多数细胞蛋白是由细胞质中核糖体生产。输出蛋白和膜蛋白通常与内质网有关。
内质网,带有花边的生物囊,有管状,泡状之分,以及光滑和粗糙面区别。两种都与蛋白质的合成和运输有关。粗糙内质网上分布许多核糖体,也可能提供细胞分裂后所需的细胞膜。
光滑内质网上无核糖体,主要作用是脂肪和类固醇的合成以及细胞内有毒物质的氧化。两种内质网合成的产物在其中进行分流或运输到细胞外。
运输小泡能够将可运输分子从内质网运输到高尔基复合体上。在高尔基复合体中修饰,包装后输出细胞或传递到细胞质中的其他场所。 细胞中的液泡好象是中空的,但实际上充满了液体和可溶分子。最典型的液泡存在于植物细胞中,储备水,糖以及其它分子。动物中的液泡起吞噬和胞饮作用。
