A nucleus also contains a nucleolus, which is essential for protein synthesis (and will be explained fully below), as well as connections to the endoplasmic reticulum and the general cellular infrastructure, allowing it to maintain control and regulation of all cell activities. In short, a nucleus...

the template chromosome remains joined to the new chromosome at a point called a centromere. The two identical joined chromosomes are called chromatids. Chromosomes are usually asymmetrical along their long axis, meaning that there is more material on one side of the centromere than on the other....

What happens during the s phase of interphase? Cells Life: A cell has a life that is similar to most of the living organisms on Earth. They are born, they grow, and they reproduce by splitting into two new cells. Cells spend most of their life in a stage known as Interphase. ...
There are about 80 different proteins in the ribosomes of eukaryotes, 50 or more of which are unique to ribosomes. As noted, these proteins account for about one-third of the overall mass of ribosomes. They are manufactured in the nucleolus inside the nucleus and then exported into the cyt...
separates the nucleus from the rest of the cell dissolves, the nucleolus disappears, and structures called centrosomes migrate to each end of the cell. The centrioles within the centrosomes sprout spindle fibers (microtubules) as they go. Some spindle fibers grab onto centrosomes as this is ...
