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. Each subunit is manufactured separately in the nucleolus. The proteins needed to make them enter the nucleus through pores in the nuclear membrane.
The nucleolus directs the assembly of proteins within the cell nucleus. The nucleolus is the part of the nucleus containing most of the genes that code for the synthesis of ri â¦ bosomal RNA (rRNA: the RNA molecules found in ribosomes).So rRNA is synthesized within the nucleolus.he Nucleolus is a 'nuclear organelle' inside of the eukaryotic Cell's nucleus. It's primary role is to synthesize messenger Rna which is rapidly exported, via the Nuclear Por â¦ es, to the nearly situated Ribosome peppered Rough Endoplasmic Reticulum.
