In eukaryotic cells, chromatin consists of all the DNA within the nucleus and its associated proteins, called histones. Eukaryotic chromosomes are composed of chromatin, and each consists of two complementary strands of DNA coiled tightly around histones. The structure of chromatin is scaffolded, with...
In eukaryotes discrete DNA molecules of between 10 4 to 10 6 kilobase pairs (Kb) in length are organised by protein into morphologically and genetically distinct units called chromosomes. The nucleoprotein material of which they are composed is generally called chromatin....
To answer the question "Eukaryotic chromosome is made of," we can break down the solution into the following steps:1. Understanding Eukaryotic Chromosomes: - Eukaryotic chromosomes are structures within the nucleus of eukar
The central nucleus contains the chromatin—the DNA genetic blueprint for the reproduction of the cell and for the synthesis of enzymes. Surrounding the nucleus is the cytoplasm. This contains many important structures (organelles), such as the MITOCHONDRIA (tiny bags containing enzymes needed for ...
Nucleoplasm – It is the fluid material in the nucleus that contains the nucleolus and chromatin. Nucleolus – Nucleoli are not membrane-bound and are active sites for ribosomal RNA synthesis. Chromatin – It consists of DNA and proteins called ‘histones’. The DNA is organised into chromosomes...

" (Figure 2). Indeed, the marbled lungfish has the largest recorded genome of anyeukaryote. Onehaploidcopy of this fish's genome is composed of a whopping 132.8 billion base pairs, while one copy of a human haploid genome has only 3.5 billion. (Genome size is usually measured in pico...
