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....
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 ...
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
" (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 picograms...
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 ...

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...

Single-nucleotide-resolution chemical RNA structure probing is emerging to explore the folding state of the transcriptome in living cells; the resulting models for how 5′ UTR structures impact translation should be validated by compensatory mutagenesis.Abstract...
Each nucleosome is linked to an adjacent one by a short segment of DNA (linker) and another histone (H1). The DNA in a nucleosome is further condensed by the formation of thicker structures called chromatin fibers, and ultimately DNA must be condensed to fit into the metaphase chromosome ...
