Uncovering the Surprising Structure and Functions of the Cell Nucleus

Nucleus of the Cell | Structure and Functions of Nucleus
The nucleus is the most important #cell #organelle bound with double-layered membranes.
The nucleus is surrounded by the endoplasmic reticulum, both rough and smooth endoplasmic reticulum. The major function of the #nucleus is to store the #hereditary information in the #dna molecule and to coordinate different activities like growth and development, #protein synthesis, and cell division. It consists of outer and inner nuclear membranes. The nuclear membrane consists of a nuclear pore that allows the selective passage of the molecules like proteins and transcripts.
The #nucleoplasm is the aqueous semi-liquid matrix found in the nucleus where nuclear material like chromatin fibers and #chromosomes are present.
For the DNA to function, they are wrapped with different histone proteins and tightly packed into compact structures to form the chromatin fibers and chromosomes.
Nucleoplasm is the site of synthesis of DNA, #RNA, and #ribosomal sub-units. And those DNA, RNA, and proteins are transported in the #cytoplasm through the nuclear pores. #Nucleolus is the small spherical dense structure found in the center of the nucleus and it is responsible for the synthesis of the ribosomes. The nucleus contains all the genetic material in the form of chromosomes.

We have studied in 7th standard now u have done the video very beautiful about Nucleus clearly
