Detailed explanation-1: -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-2: -Every cell in the human body carries a bundle of DNA in its nucleus-about three billion chemical nucleotides encoding roughly 30, 000 genes, discrete chunks of DNA that are translated into individual proteins. Each of the 46 chromosomes in a human cell’s nucleus bears thousands of genes.
Detailed explanation-3: -The nucleus is a membrane-enclosed organelle, found in most eukaryotic cells, which stores the genetic material (DNA). The nucleus is surrounded by a double lipid bilayer, the nuclear envelope, which is embedded with nuclear pores. The nucleolus is inside the nucleus, and is where ribosomes are made.
Detailed explanation-4: -The primary functions of the nucleus are to store the cell’s DNA, maintain its integrity, and facilitate its transcription and replication.
