Which of the following is not true of the nucleus of a living cell? It...

Explanation

The question is asking which statement about the nucleus of a living cell is not true. The options listed are A) chromosomes, B) nucleolus, C) nucicoplasm, D) chromatids (which is the correct answer), and E) ribosome. The nucleus is a membrane-bound organelle found in eukaryotic cells, which contains the genetic material of the cell. It is often referred to as the control center of the cell because it regulates gene expression and DNA replication. Chromosomes are structures found in the nucleus that contain genetic information in the form of DNA. The nucleolus is a region within the nucleus that is responsible for the production of ribosomes. Nucicoplasm refers to the jelly-like substance that makes up the majority of the nucleus. Chromatids are two identical copies of a chromosome that are joined at a point called the centromere. During cell division, chromatids separate and move to opposite poles of the cell. Therefore, statement D is not true of the nucleus because chromatids are not a permanent feature of the nucleus, but rather a temporary structure that forms during cell division. Ribosomes, on the other hand, are not found in the nucleus but are located in the cytoplasm or attached to the endoplasmic reticulum. They are responsible for protein synthesis. In summary, the nucleus of a living cell contains chromosomes, nucleolus, and nucicoplasm, but does not contain chromatids. Ribosomes are not found in the nucleus.
