WebEach chromosome consists of a single very long DNA molecule that has been compacted approximately 10,000-fold by interactions with proteins, such that the resulting chromosome structure fits within a typical eukaryotic nucleus of only 10 microns in diameter. Several levels of structural organisation are involved in the formation of … WebChromatin consists of all the DNA in the nucleus, as well as its associated proteins. There are three basic layers of chromatin scaffolding that results in a condensed DNA molecule. The double helix shaped DNA molecule …

WebIf the breaks occur on different chromosome arms the inverted section includes the centromere and the result is a per i centric inversion (peri = around). No genetic material has been lost in this rearrangement. Figure 5.2. 3 c: Duplications can occur from when DNA breaks at different places in sister chromatids. WebYour DNA structure is made up of four base pairs: adenine (A), cytosine (C), thymine (T), and guanine (G). The bases form pairs (base pairs); A with T and C with G. The base pairs connect with a sugar molecule and a phosphate molecule (making a nucleotide) that form a spiral staircase (double helix).
