aNearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitohondrial DNA or mtDNA). 几乎每个细胞在人的身体有同样脱氧核糖...
(In prokaryotes the hereditary material is found in the nucleoid.) The nucleus also contains one or two organelles-the nucleolithat play a role in cell division. 真核细胞核是最大的细胞器,其容纳在染色体上的遗传物 质(DNA)。(在原核生物中,遗传物质发现于类核中。)细 胞核还包含一个或两个细胞...
Cells in obligately multicellular organisms by definition have aligned fitness interests, minimum conflict, and cannot reproduce independently. However, some cells eat other cells within the same body, sometimes called cell cannibalism. Such cell-in-cell
Cells with thinner rod-shaped nuclei with smooth parallel sides are called bands (seeFig. 8-13,K,O,S). No area of the nucleus has a diameter less than two-thirds the diameter of any other area of the nucleus. Bandcell nucleitwist to conform to the space within the cytoplasm, and hors...
2、e cell and so on.,Cytoplasm The cytoplasm is basically substance that fills the cell and located out side the nucleus. It contains organelles and inclusions in An aqueous gel called the cytoplasmic Matrix.,Nucleus Is a membrane bound structure that containes the cells hereditary information an...
A circular region of 36 × 36 pixels was digitally made to fit the centre of the cell nucleus and ablated with a dwell time of 1.58 μs per pixel at 70% laser power within a stack of 16 slices, for one iteration, under software control. This spatial and temporal focal ...

Histone modifications The nucleus contains the chromosomes of the cell. Each chromosome consists of a single molecule of DNA complexed with an equal mass of proteins. Collectively, the DNA of the nucleus with its associated proteins is called chromatin. chromosome Nucleosome Structure of chromatin ...
Let's start with the nucleus, the control center of the cell. 让我们从细胞核,细胞的控制中心开始。 The nucleus contains DNA or genetic material. 细胞核含有DNA或遗传物质。 DNA dictates what the cell is going to do and how it's going to do it. ...
nucleus17,19. Degradation of one or more genome segments, following nuclear import and prior to transcription could also occur4. Since each genome segment encodes at least one viral protein, degradation of only one of them means failure to cause a productive cell infection. There is also a ...
