There are many different types of APIs for operating systems, applications or websites. Windows, for example, has many API sets that are used by system hardware and applications â when you copy and paste text from one application to another, it is the API that allows that to work.
Function of the Nucleolus. Ribosomes are made of two subunits, a large and a small. Each subunit is manufactured separately in the nucleolus. The proteins needed to make them enter the nucleus through pores in the nuclear membrane. The rRNA is made in the nucleolus itself.ibosomes are made of two subunits, a large and a small.

The nucleolus is by far the most easily recognized substructure in the eukaryotic nucleus, and can be seen by using a variety of dyes as well as by phase contrast microscopy.Indeed, in budding yeast, the single nucleolus takes up nearly half of the nucleus. Cells from other species often have multiple nucleoli.The nucleolus is a ribosome factory, composed of deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and protein.ndeed, in budding yeast, the single nucleolus takes up nearly half of the nucleus.
