What is Kanekalon made of? A: Kanekalon, a lighter and softer hair used globally for synthetic wigs and extensions, consists of a type of synthetic fiber known as modacrylic fiber. These fibers are modified acrylic fibers that stem from acrylonitriles and vinyl chloride. Continue Reading.
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
RNA is, in fact, the second of the two types of nucleic acids; however, there are a number of structural differences between the two. First let's address the name. Like DNA, RNA is a nucleic acid composed of a sugar, a phosphate group and a nitrogenous base. One difference between DNA and RNA is the sugar.his type of RNA is called ribosomal RNA, or rRNA. Remember that DNA and RNA differ slightly at the nucleotide level. Therefore, the process of transcribing DNA into RNA not only changes the information from a double-stranded into a single-stranded molecule, but also changes all the thymine bases into uracil ones.
