Chromosomes are made up of chromatin. Chromatin made up of the threads of DNA forms the structure of chromosomes. The DNA gets condensed to form chromosomes. Genes are the segments of DNA. The code for proteins. This means chromosomes are made up of DNA which contains man...
The nucleus is a cellular organelle that is only present in eukaryotes. Its main function is to regulate gene expression; it also controls cellular growth and replication. DNAOne of the main functions of the nucleus is to carry DNA in the form of chromatin. It also duplicates DNA. While euk...

mitosis. Chromatin is composed ofDNAand skeletalproteinsand is called a nucleosome when wrapped around these proteins in sequence. Even more tightly wound nucleosomes are called chromatin fibers. Chromatin condenses DNA enough to fit within a cell's nucleus. Condensed chromatin fibers form chromosomes...
