4 lut 2021 · The nucleus is a double membrane-bound organelle that contains the genetic material of eukaryotic cells. It controls and coordinates the cell processes, such as metabolism, growth, and division, and also synthesizes ribosomes and regulates gene expression.
The cell nucleus is a membrane-bound organelle that contains most of the cell's DNA and controls gene expression. It is surrounded by the nuclear envelope, which has pores that regulate the transport of molecules across it.
8 paź 2024 · It controls the activities of the cell, playing essential roles in gene expression, DNA replication, RNA processing, and transport between the nucleus and cytoplasm. The nucleus consists of the nuclear envelope, nuclear pore complexes, nucleolus, nuclear lamina, nucleoplasm, and chromatin.
8 kwi 2024 · Function and Activity The primary function of the nucleolus is the transcription of rRNA and the assembly of ribosomes, the cell’s protein synthesis machinery. It is also involved in the modification, processing, and folding of pre-rRNA into mature rRNA.
30 lip 2017 · The cell nucleus is a large organelle that protects and processes the DNA in eukaryotic cells. It produces RNA and proteins for the cell, and varies in shape and size depending on the organism and cell type.
The presence of a nucleus is the principal feature that distinguishes eukaryotic from prokaryotic cells. By housing the cell's genome, the nucleus serves both as the repository of genetic information and as the cell's control center.
