GENERAL HISTOLOGY

Detailed explanation-1: -The primary functions of the nucleus are to store the cell’s DNA, maintain its integrity, and facilitate its transcription and replication.

Detailed explanation-2: -It stores the cell’s hereditary material, or DNA, and it coordinates the cell’s activities, which include intermediary metabolism, growth, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.

Detailed explanation-3: -Plant cells have a cytoplasm, cell membrane and nucleus which all perform the same functions as animal cells. Many people think that plant cells do not contain mitochondria, but of course they do! Mitochondria are needed to release energy from sugar, plant cells need this energy to function just as animal cells.

Detailed explanation-4: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center. DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.

Detailed explanation-5: -The nucleus has 2 primary functions: It is responsible for storing the cell’s hereditary material or the DNA. It is responsible for coordinating many of the important cellular activities such as protein synthesis, cell division, growth and a host of other important functions.
