The tallest artificial structure is Burj Khalifa, a skyscraper in Dubai that reached 829.8 m (2,722 ft) in height on January 17, 2009. By April 7, 2008 it had been built higher than the KVLY-TV mast in North Dakota, USA.
The nucleolus is a round body located inside the nucleus of a eukaryotic cell. It is not surrounded by a membrane but sits in the nucleus. The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. It then sends the subunits out to the rest of the cell where they combine into complete ribosomes.
There are a few differences between the nucleus and nucleolus. To better differentiate the two parts of the cell, we should consider the functions, structures, and other features of these cellular organelles. Basically, the nucleolus is just a part of the nucleus.The nucleus is the main part of the cell while the nucleolus is part of the nucleus itself. The nucleus is a membrane-bound organelle that is found in multi-celled organisms or eukaryotes.This membrane that encloses the nucleus has two parts. The parts of the membrane are the inner and outer cellular membrane..The nucleus is membrane bound while the nucleolus is non-membrane bound. 3.The nucleus contains DNA while the nucleolus contains RNA. 4.The nucleus has the chromosomes and cellular membranes while the RNA has the fibrillar centers, dense fibrillar centers, and the granular component.
