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 three distinct levels. First, the DNA is wrapped around clusters of histones, forming nucleosomes that are connected ...
Chromatin is composed of: a) DNA. b) DNA and proteins. c) DNA, RNA and proteins. d) None of the above In eukaryotes. DNA is wrapped with proteins, forming a complex called chromatin. There are 5 types of histone proteins in chrom...
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 ...
In females, one of the two X chromosomes is inactivated during embryonic development because of epigenetic changes to the chromatin. What impact do you think these changes would have on nucleosome packing? Show Answer How the histone proteins move is dependent on signals found on both the histone...
Chromosomes are only visible and distinguishable from one another when the cell is getting ready to divide. When the cell is in the growth and maintenance phases of its life cycle, the chromosomes resemble an unwound, jumbled bunch of threads, which is the chromatin. ...
Does a retrovirus have a genome made of RNA? Chromatin contains proteins called Do archaea have single-stranded DNA? What cell part contains an organism's genome? Does DNA polymerase require ATP? Is a chromatid a single-stranded DNA?

One such organelle is the nucleus that houses the genetic encoding (DNA, chromatin) and is contained by a separate lipid membrane isolating the DNA from the other organelles contained by the larger cell membrane. Examples of organelle machinery include the mitochondria that convert stored chemical ...
