We walk you through thefunctions of the cell membrane,endoplasmic reticulum, andvacuoles. If you learn better by looking at the big picture, you'll also want to keepour complete guide to animal cellshandy so you can refer back to it while reading about each individual cell structure. If you...
Cells use active cytoskeletal structures to perform essential processes such as cell division, cell motility, force generation and morphogenesis1,2. Cytoskeletal structures consist of dynamic filaments that are cross-linked by molecular motors and rely on constant energy consumption for their assembly and...
1 The different metaphase I cell types expected in respect to the constitution of their chromosome 1R (showing or not evidence of recombination in the two arms) and the minimum number of chiasmata necessary for their appearance. As chromosome pair 1R was heterozygous for the presence of ...
It is still unclear what makes rat eggs susceptible to spontaneous activation; however, a vague picture of the signalling pathways involved in the process of spontaneous activation is beginning to emerge. Such cell cycle instability is one of the major reasons why it is more difficult to ...
