I think the answer are:
1) J is cytoplasm and K is nucleoplasm.
2) full form of M is deoxyribo nucleic acid.
3) N is the genes. its function is it transfers the hereditary characters from one generation to another, from one person to th other. they are the unit of heredity.
hope it helps..

Answer:
In this question, we are given information about a cellular structure called X, which is popularly known as the brain of the cell. Let's break down the information and answer the given questions:
1. Name J and K:
- J: The information does not provide a specific name for J. However, based on the context, J is most likely referring to the cytoplasm. The cytoplasm is the gel-like substance that fills the cell and surrounds the organelles.
- K: K is the liquid ground substance enclosed by the double-layered covering Y. This substance is known as the nucleoplasm. The nucleoplasm is found within the nucleus of a cell and contains various components necessary for the functioning of the nucleus.
2. Full name of M:
- The full name of M is chromatin. Chromatin is a complex of DNA, RNA, and proteins found within the nucleus of a cell. It plays a crucial role in packaging DNA and regulating gene expression.
3. Identify N and describe its function:
- N refers to functional segments of M, which are called nucleosomes. Nucleosomes are the basic units of chromatin. Each nucleosome consists of DNA wrapped around a core of proteins called histones. The function of nucleosomes is to compact the DNA and regulate access to the genetic information contained within the DNA molecule.
- Nucleosomes play a vital role in gene expression by controlling the accessibility of genes for transcription. They can either facilitate or inhibit the binding of transcription factors and other regulatory proteins to DNA, thereby influencing gene expression levels.
- Additionally, nucleosomes also help in the organization and stability of chromosomes during cell division.
Summary:
- J refers to the cytoplasm, and K refers to the nucleoplasm.
- M is the chromatin, which is a complex of DNA and proteins.
- N represents nucleosomes, which are functional segments of chromatin.
- Nucleosomes play a crucial role in gene expression and the organization of chromosomes during cell division.
