Chromosomes are coiled structures made of DNA and proteins. Chromosomes are encoded with genetic instructions for making proteins. These instructions are organized into units called genes. Most genes contain the instructions for a single protein. There may be hundreds or even thousands of genes on a single ...

Figure 03-03: DNA in the interphase nucleus is organized and packaged. First, the DNA is wrapped around core histones to form nucleosomes. H1 then helps loop nucleosomes together into a fiber, which then can be further looped and packaged inside the nucleus in a highly organized manner.In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be "opened" so that specific genes are expressed.

H1 then helps loop nucleosomes together into a fiber, which then can be further looped and packaged inside the nucleus in a highly organized manner.What are chromosomes: The DNA molecules are tightly packaged within a nucleus with the help of the thread-like structure is known as chromosomes. Each chromosome is made by DNA tightly coiled many times around the proteins, known as Histones which help to support its structure. Each chromosome has a constriction point known as the Centromere ...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.In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Explanation:

The center of a chromosome that holds two chromatids together, also where spindle fibers are attached during division. What is a chromatid? Half of an x-shaped chromosome. One chromatid is replicated to make an x-shaped chromosome. What is a chromosome? (two answers) One chromatid, combined with a centromere (called a single-stranded chromosome).

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.First, chromosomes are composed of an original and a replicated chromatid, called sister chromatids. Chromatids are composed of tightly packed DNA. DNA is replicated after the end of the S-phase, or in other words, the material composing the two sister chromatids is there.
