RNA和DNA的区别,什么是原核生物什么是真核细胞?如有英文回答就更好,
RNA是由四种核糖核苷酸组成的,DNA是由四种脱氧核糖核苷酸组成的.
RNA是单链结构,DNA是双螺旋结构
原核生物与真核生物的区别是,有无以核膜为界限的细胞核
原核生物是没有核膜,也就是没有成形的细胞核的,真核细胞有核膜,也就是有成形的细胞核的例如动植物的细胞,还有真菌的细胞都是真核的
RNA is composed of four kinds of ribose nucleotide composition,DNA is composed of four kinds of deoxyribose nucleotide composition.RNA is a single structure,DNA double helix structureProkaryotes and eukaryotes difference is there to the nuclear envelope,to the limits of the nucleusProkaryotes are the absence of a nuclear membrane,there is no forming the nucleus of eukaryotic cells,with the nuclear envelope,is forming the nucleus such as animal and plant cells,and fungi are eukaryotic cells

the differences between DNA and RNA
1 RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom)
2 and RNA has the nucleobase uracil while DNA contains thymine.
3 RNA is a single-stranded molecule in many of its biological roles and has a much shorter chain of nucleotides.
The prokaryotes are a group of organisms that lack a cell nucleus, or any other membrane-bound organelles.
A eukaryote is an organism whose cells contain complex structures enclosed within membranes.The defining membrane-bound structure that sets eukaryotic cells apart from prokaryotic cells is the nucleus, or nuclear envelope, within which the genetic material is carried. Most eukaryotic cells also contain other membrane-bound organelles such as mitochondria, chloroplasts and the Golgi apparatus.
