Chapter 9 and some of 8DNA and the Molecular Structure
of Chromosomes
The Structures ofDNA and RNA
DNA is usually double-stranded, with
adenine paired with thymine
and guanine paired with
cytosine. RNA is usually single-
stranded and contains uracil in
place of thymine.
WhenDo weFind RNAMixed with The DNA?
nucleoside = sugar +base
nucleotide = sugar + base + phosphate
Ribonucleotide Reductase
Pyrimidines have the longer name and smaller basePurines have the shorter name and bigger base
