WebTypically, the nucleus is the most prominent organelle in a cell. The nucleus (plural = nuclei) houses the cell’s DNA in the form of chromatin and directs the synthesis of ribosomes and proteins. Let us look at it in more detail ( Figure 3.11 ). Figure 3.11 The outermost boundary of the nucleus is the nuclear envelope. WebComparison to the in situ structure that shows similar resolution of the extra- and intracellular regions, suggests that the structural flexibility and position of “cytosolic map 1” far away from the membrane is most likely a preparation artifact of the purified monomeric CatSper complex that lacks the dimer-interactions and native membrane.
