The above account gives patterns of coiling and packing of DNA. Since 60 nm (600 Å) long DNA (166 base pairs) is coiled in a nucleosome, only 5.5 nm (55 Å) long, and then nucleosomes are coiled in 30 nm (300 Å) wide solenoid fibres, it gives DNA a packing ratio of 1 : 50. However, in highly condensed chromosomes, the packing ratio is actually 1 : 5,000, which is 100 times greater than provided by solenoid model. This 100 times packing of the solenoid, should take place by further coiling and folding of solenoid]]> 2020-09-28 14:53:04 UTC https://padlet.com/moreankita2014/ctjt8to7yhmcd9we/wish/784632756 moreankita2014 https://padlet.com/moreankita2014/ctjt8to7yhmcd9we/wish/785055702 Introduction:
The arrangement of DNA on chromosome through nucleosome assembly is known as DNA packaging.
Packaging here refers to the condensing od DNA to fit easily into the nucleus.
The length of DNA in the nucleus is far greater than the compartment in which it is contained.
Condensation of DNA is necessary to fit into the nuclear compartment.]]> 2020-09-28 16:34:01 UTC https://padlet.com/moreankita2014/ctjt8to7yhmcd9we/wish/785055702
