The size of the nucleus is correlated to the size of the cell, and this ratio is reported across a range of cell types and species. [9] In eukaryotes the nucleus in many cells typically occupies 10% of the cell volume. [10]: 178 The nucleus is the largest organelle in animal cells.
Macronuclei and micronuclei differ in their functions even though they are located within the same cell. The micronucleus is globally repressed during the vegetative state , and serves as the diploid germline nucleus, whereas all known vegetative gene expression happens in the macronucleus, which is a polyploid somatic nucleus.

Nucleus: The nucleus of the cell functions as the genome and genetic information storage for the cell, containing all the DNA organized in the form of chromosomes. It is surrounded by a nuclear envelope, which includes nuclear pores allowing for the transportation of proteins between the inside and outside of the nucleus. [15]
Cell nucleus: A cell's information center, the cell nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell's chromosomes , and is the place where almost all DNA replication and RNA synthesis ( transcription ) occur.
The principal function of nuclear pore complexes is to facilitate selective membrane transport of various molecules across the nuclear envelope. This includes the transportation of RNA and ribosomal proteins from the nucleus to the cytoplasm , as well as proteins (such as DNA polymerase and lamins ), carbohydrates , signaling molecules , and ...
Many dogs feel their best when they have a have a job to do, whether it's a quick task or an all day undertaking. In fact, plenty of dogs were bred to do jobs, like the Siberian Huskies who pull ...
In neuroanatomy, a nucleus (pl.: nuclei) is a cluster of neurons in the central nervous system, [1] located deep within the cerebral hemispheres and brainstem. [2] The neurons in one nucleus usually have roughly similar connections and functions. [ 3 ]
A New Jersey family is suing DraftKings after a father of two gambled away more than $1 million of his family’s money across four years. The man, known by his username Mdallo1990, allegedly lost ...
