Chromosomes are made of tightly packed ________ molecules..
3 days ago · The human X chromosome is about three times larger than the human Y chromosome, containing about 900 genes, while the Y chromosome has about 55 genes. The unique structure of chromosomes keeps DNA tightly wound around spool-like proteins, called histones. Without such packaging, DNA molecules would be too long to fit inside cells!
A chromosome is a package of DNA with part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome -forming packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA ...

This DNA is tightly packed into structures called chromosomes, which consist of long chains of DNA and associated proteins. In eukaryotes, DNA molecules are tightly wound around proteins - called histone proteins - which provide structural support and play a role in controlling the activities of the genes.
Chromosome I contains most of the essential genes, while chromosome II only carries a few essential functions and is probably derived from a megaplasmid [Heidelberg et al., 2000]. The replication origins of these two chromosomes localize to distinct positions during all stages of the cell cycle [Fogel and Waldor, 2005]. The origin …Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromatin is located in the nucleus of our cells . The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus.A DNA molecule is made up of a s eries of nucleotides arranged in 2 strands that resemble a ladder and twist to form a double helix. Nucleotides are made up of a base, a sugar and a phosphate. The 4 bases – adenine (A), guanine (G), cytosine (C) and thymine (T) – pair with each other (A with T and G with C).
