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 ... Humans have around 22,000 genes on 46 chromosomes. Chromosomes are highly organized structures that hold genetic information in the form of DNA. These structures reside within the nucleus of a cell. The DNA is tightly packed to make up the chromosomes, utilizing molecules known as histones to assist in this packing.

A cell’s DNA, packaged as a double-stranded DNA molecule, is called its genome. In prokaryotes, the genome is composed of a single, double-stranded DNA molecule in the form of a loop or circle (Figure 12.2.1 12.2. 1 ). The region in the cell containing this genetic material is called a nucleoid (remember that prokaryotes do not …Chromosome Structure The DNA structure of a human cell is packed even more tightly.

Eukaryotic chromosome is made up of tightly coiled and condensed DNA around clusters of nuclear proteins called histones. Histone helps in the packaging of DNA into a closely-packed form and that's how it fits in the cell's nucleus. Genes are part of cell structures called chromosomes. In multicellular organisms, chromosomes are found in the nucleus of the cell. Each of these chromosomes contains one, long molecule of DNA, or d eoxyribo n ucleic a cid. A gene is a specific stretch of this DNA molecule. Each chromosome in the cell contains many genes. The 46 chromosomes of a human cell are organized into 23 pairs, and the two members of each pair are said to be homologues of one another (with the slight exception of the X and Y chromosomes; see below). Human sperm and eggs, which have only one homologous chromosome from each pair, are said to be haploid ( 1n ). Winston Cahya. 49 3 5. They don't pack into chromosomes.
