Question

Where does transcription and translation occur in a Neuron?

Answer 1

ANSWER :

Transcription and translation occur in cell body in a Neuron.

EXPLANATION :

Neurons different from other cells in the body
because they express specific genes as proteins.

The cell body is filled with nucleus, ribosomes, and specialized organelles such as the mitochondria, Golgi apparatus, endoplasmic reticulum, secretory granules, ribosomes and polysomes which help in protein synthesis.

The cell body produces proteins for the dendrites, axons and synaptic terminals.

The process protein synthesis begins in the nucleus of the cell. The nucleus is separated from the intracellular fluid and other organelle of the cell and contain genetic information that guides cellular function. The genetic information is stored in DNA. Each DNA molecule has the genetic codes for all the cells in the body but only a selected part of DNA is used by nerve cells.

The nucleus begins the process of transcription of DNA code into a complementary RNA. RNA then released by the nucleus into the intracellular fluid surrounding it, where the process of protein synthesis ( translation) takes place.

Nissl Bodies is a large granular body found in neurons. They are the groups of ribosomes used for protein synthesis. These granules are of rough endoplasmic reticulum (RER) ,are the site of protein synthesis.

The nucleolus is a separate structure within the nucleus, which is also involved in the process of protein synthesis but does not manufacture proteins directly. But it builds ribosomes that are involved in protein synthesis. Ribosomes are complexes of RNA and protein that come outside from the nucleolus and nucleus into the cell body, where they perform their work....
