真核DNA更緊密的狀態(tài)是螺線管形式（solenoid form）。與核小體結(jié)合的組蛋白H1誘導(dǎo)其組裝成6個(gè)核小體的環(huán)，并且這些環(huán)組成圓筒狀螺線管結(jié)構(gòu)。在分裂間期大多數(shù)真核染色體以螺線管形式存在。進(jìn)行復(fù)制或被表達(dá)的（轉(zhuǎn)錄為RNA分子）這些部分去解凝成為伸展的核小體形式。DNA的復(fù)制發(fā)生在間期的S階段。基病毒表達(dá)發(fā)生在間期的所有階段（G0、S和G1）。那些不進(jìn)行增殖的（進(jìn)入細(xì)胞周期）真核細(xì)胞被認(rèn)為是在G0階段，并且與間期細(xì)胞相似。在間期細(xì)胞核中看到的染色質(zhì)是由絕大多數(shù)以螺線管形式存在的DNA 構(gòu)成。
DNAzui緊密的狀態(tài)是環(huán)狀的螺線管形式。DNA結(jié)合蛋白促進(jìn)螺線管在支架蛋白中心核前后形成環(huán)狀。在一些真核生物中螺線管的l8個(gè)環(huán)組成了一個(gè)盤狀結(jié)構(gòu)。染色體凝聚為數(shù)百個(gè)病毒在一起的盤狀結(jié)構(gòu)。在有絲分裂和減數(shù)分裂的過(guò)程中，可觀察到環(huán)狀的螺線管形式。由于許多長(zhǎng)的染色體必須在細(xì)胞內(nèi)移動(dòng)，并且在移動(dòng)過(guò)程中可能被牽扯，所以染色體的濃縮是必要的。[2] 
原核細(xì)菌
在高中階段，染色體必須由DNA和蛋白質(zhì)組成。由于原核生物的染色體一般不含組蛋白，所以高中階段稱原核生物沒(méi)有染色體。
一般而言，原核生物的染色體可以進(jìn)行復(fù)制，但大多數(shù)細(xì)胞容易存活多份。
所有必需的細(xì)菌基病毒存在于細(xì)胞質(zhì)中的單個(gè)環(huán)狀雙鏈DNA（dsDNA）染色體中。細(xì)菌染色體與質(zhì)膜相附著。細(xì)菌染色體（bacterial chromosome）依其種類不同可編碼1000個(gè)或5000 個(gè)蛋白質(zhì)。除了細(xì)菌染色體以外，還可有一個(gè)或多個(gè)較小的染色體，稱為質(zhì)粒，它一般 20一100個(gè)蛋白質(zhì)。質(zhì)粒是環(huán)狀雙鏈DNA分子，它可與或不與質(zhì)膜附著。質(zhì)粒編碼的大多數(shù)或全部蛋白質(zhì)在正常環(huán)境條件下并不是細(xì)胞生存所必需的。許多質(zhì)粒編碼的蛋白質(zhì)使其把一些病傳信息向其他細(xì)胞轉(zhuǎn)移成為可能，并促進(jìn)稀有病毒合物的代謝。或使細(xì)胞可抵抗某些病毒學(xué)物質(zhì)或重金屬。

A more compact state of eukaryotic DNA is a solenoid form. Histone H1, which binds to nucleosomes, induces it to assemble into a loop of 6 nucleosomes, and these loops form a cylindrical solenoid structure. Most eukaryotic chromosomes exist in the form of solenoids during the interphase. These parts that are replicated or expressed (transcribed as RNA molecules) de-coagulate into an extended nucleosome form. DNA replication occurs in the interphase S phase. Viral expression occurs at all stages of the interphase (G0, S, and G1). Eukaryotic cells that are not proliferating (entering the cell cycle) are thought to be in the G0 phase and are similar to interphase cells. Chromatin, seen in the interphase nucleus, consists of most of the DNA in the form of a solenoid.
The DNA's closest state is a toroidal solenoid. DNA-binding proteins promote the formation of a loop of solenoids around the central core of the scaffold protein. In some eukaryotes, the l8 rings of the solenoid make up a disk structure. Chromosomes aggregate into hundreds of virus-like discoid structures. In the process of mitosis and meiosis, a circular solenoid can be observed. Chromosome condensation is necessary because many long chromosomes must move within the cell and may be involved during the movement. [2] 
Prokaryotic bacteria
In high school, chromosomes must consist of DNA and protein. Because prokaryotes usually do not contain histones, so in high school, prokaryotes have no chromosomes.
In general, prokaryotic chromosomes can replicate, but most cells tend to survive in multiple copies.
All of the necessary bacterial-based viruses are present in a single circular double-stranded DNA (dsDNA) chromosome in the cytoplasm. Bacterial chromosome attached to the plasma membrane. Bacterial chromosomes can encode 1000 or 5000 proteins depending on their type. In addition to bacterial chromosomes, there may be one or more smaller chromosomes, called plasmids, which typically specify between 20 and 100 proteins. Plasmids are circular double-stranded DNA molecules that can be attached to or not attached to the plasma membrane. Most or all of the proteins encoded by plasmids are not absoluy required for cell survival under normal environmental conditions. Many plasmid-encoded proteins make it possible to transfer some of the pathogenic information to other cells and to promote the metabolism of rare viral compounds. Or make cells resistant to certain virological substances or heavy metals.
