How Do You Spell NUCLEAR PORE?

Pronunciation: [njˈuːkli͡ə pˈɔː] (IPA)

The spelling of "nuclear pore" can be explained through its phonetic transcription in IPA. The first syllable "nu" is pronounced as "nju" with the "j" sound being a glide between the "n" and "u". The second syllable "cle" is pronounced as "klɛ". The third syllable "ar" is pronounced as "ɑr". Lastly, the word ends with "pore" pronounced as "pɔr". Therefore, the correct spelling of this term is "nuclear pore", accurately reflecting its pronunciation. The term refers to a protein-lined channel in the nuclear envelope that allows for the transport of materials between the nucleus and cytoplasm of a cell.

NUCLEAR PORE Meaning and Definition

1. A nuclear pore is a highly specialized structure found within the nuclear envelope of eukaryotic cells. It acts as a gateway or transport channel that regulates the movement of molecules, such as proteins and RNA, between the nucleus and the cytoplasm.

   The nuclear envelope is a double membrane structure that surrounds the nucleus, separating its contents from the cytoplasm. This barrier prevents the unregulated exchange of molecules, as it is crucial for maintaining the integrity and functionality of the nucleus. The nuclear pore serves as a selective barrier, allowing only specific molecules to enter or exit the nucleus.

   A nuclear pore has a complex structure composed of different proteins, known as nucleoporins, which form a large, cylindrical structure with a central channel. This channel creates a pathway for molecules to pass through, but it is also heavily regulated by the cell to ensure only certain substances are allowed to cross.

   The size and shape of the nuclear pore are such that it can accommodate the transport of relatively small molecules, such as ions, as well as larger macromolecules, like proteins and RNA. The selective permeability of the nuclear pore is achieved through signal recognition and interaction with specific receptor proteins, which dictate whether a molecule can dock onto the pore and pass through.

   The nuclear pore is therefore a crucial component of the eukaryotic cell, as it forms a communication channel between the nucleus and the cytoplasm, enabling the controlled movement of molecules essential for various cellular processes, including gene expression, RNA processing, and protein synthesis.

Etymology of NUCLEAR PORE

The word "nuclear" originates from the Latin word "nucleus", meaning "kernel" or "core". It was first used in English in the early 19th century to refer to the central part or core of something. In the context of biology, "nuclear" refers to the nucleus of a cell, which is the organelle that contains the genetic material.

The word "pore" has its roots in the Latin word "porus", meaning "passage" or "opening". It was used in English from the late 14th century to denote a small opening or hole, often associated with the skin or a membrane.

The term "nuclear pore" was coined by the scientists Michael Watson and John Gerace in the 1980s to describe the protein structures found on the nuclear envelope of cells.
