Hint: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 contain...

The first step is wrapping the DNA double helix sections around histone proteins to form structures called nucleosomes. Nucleosomes are linked into structures called "beads on a string" form of chromatin. "beads on a string" chunks are packaged into supercoiled structures call chromosome fibre. ...
- 《Molecular & Cellular Biology》 被引量: 125发表: 1990年 Intra- and inter-nucleosome interactions of the core histone tail domains in higher-order chromatin structure Eukaryotic chromatin is a hierarchical collection of nucleoprotein structures that package DNA to form chromosomes. The initial ...
whereas in chromosomes they are callednucleosomes. A nucleosome is a histone-DNA complex. These were discovered when scientists used caustic materials to dissolve the outer proteins from chromosomes, leaving behind chromatin containing only histones and DNA. Chromatin offers a "beads on a string" app...
What is the difference between chromatin and histone? How do you simplify 8^5/6? Identify the normal structure and function of the cardiovascular system. What is the plot structure of Animal Farm? What is the difference between replication and duplication in chromosomes?
Here, the strands of DNA are found around proteins known as histones to form nucleosomes that coil to form chromatins. In some cases, however, the DNA is wound around non-histone chromosomal proteins. Based on molecular studies, researchers have shown that each of the nucleosomes consists ...
The evolution of plants to efficiently transport water and assimilates over long distances is a major evolutionary success that facilitated their growth and colonization of land. Vascular tissues, namely xylem and phloem, are characterized by high specia
Describe the base-pairing rules in any DNA molecule. What is the meaning of chromatin? Draw the DNA structure and explain why the DNA strands are antiparallel. Explain the link between DNA sequence and protein structure and function. The shape of DNA is commonly referred to as a what?
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...
