Chromosomes are made of tightly packed ________ molecules..

Jul 16, 2018 · When the DNA in a chromosome is tightly packed, it takes on a configuration that resembles an X, or in the case of the male sex chromosome, a Y. Each individual chromosome is made of two telomeres, which make up the sides of the X, and a specialized sequence of DNA, called a centromere, that acts as a band holding the centers of the two ... 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.DNA Packing: DNA is so lengthy; it requires special packaging. The DNA must be packaged properly to accommodate inside the nucleus. The cells coil their DNA across scaffolding proteins to produce chromatin, a compact structure. Chromatin is stretched further to form various structures, which finally become chromosomes.A quick overview. Chromosomes are bundles of tightly coiled DNA molecules.

Human Chromosomes. Human cells normally have two sets of chromosomes, one set inherited from each parent. There are 23 chromosomes in each set, for a total of 46 chromosomes per cell. Each chromosome in one set is matched by a chromosome of the same type in the other set, so there are actually 23 pairs of chromosomes per cell.

The nucleus houses the genetic material of the cell: DNA. DNA is normally found as a loosely contained structure called chromatin within the nucleus, where it is wound up and associated with a variety of histone proteins. When a cell is about to divide, the chromatin coils tightly and condenses to form chromosomes.DNA is packed into chromosomes in the form of chromatin, also know as supercoiled DNA. And so, chromatin is made up of DNA, histone proteins, and non-histone proteins. And there are repeating units in chromatin, called nucleosomes, which are made up of 146 base pairs of double helical DNA that is wrapped around a core of eight histones.The result of _________ is the division of a cells chromosomes into two new nuclei, each of what has the same amount and type of DNA as the original nucleus.
