答案:Mitochondria are often referred to as the "powerhouses" of the cell because they generate most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy. They are unique among cellular organelles because they have their own mitochondrial DNA and ...

DNA(脱氧核糖核酸)是由核苷酸组成的长链分子,通过碱基配对形成双螺旋结构,以基因形式存储遗传信息,并通过复制和表达控制生物性状。 1. **定义验证**:DNA全称符合脱氧核糖核酸,其化学组成(脱氧核糖、磷酸基团、含氮碱基)及双螺旋结构为生物学共识。2. **信息存储机制**:DNA的碱基序列(A-T、C-G配对)直接编码遗传...
Here we tested the possible role of DNA methylation in mediating long-term induction of epileptiform activity by transient kainic acid exposure using in vitro and in vivo rodent models. We analyzed changes in the gria2 gene, which encodes for the GluA2 subunit of the ionotropic glutamate, alpha...
Scientists have spotted unique subtypes of fat cells in the human body, and by unraveling their functions, they found that the cells may play a role in obesity. The research, published Jan. 24 in the journal Nature Genetics, could theoretically open up avenues for new therapies to mitigate do...
What are the benefits of reading these cousin quotes? Cousins are always there for us when we need them; they can even help us find ourselves through their crazy antics. The cousin quotes below: Will explore this unique relationship and the important role cousins play in families ...
- It controls the activities of the cell by regulating gene expression. This means it determines which proteins are made and when, thus influencing cell function and behavior.- The nucleus also plays a role in cell division. During cell division, chromatin condenses to form chromosomes, which ...
EMehi TAKAHASHI, Tada-ak~HORI (Div. Genet., Natl. Inst. Radiol. Sci., Chiba) and Motoi MURATA (Div. Epidemiol., Chiba Cancer Cent., Chiba) Heritable (rare) fragile sites (FS or fra) on human chromosomes are of great interest, because they may play a potential role in inducing ...
