Standard 4 exon gene
-Where is the polyA tail in the gene above?-Draw a 4 exon gene where exon 4 is all 3’UTR
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
QuickTime™ and a decompressor
are needed to see this picture.

Chain
Why do weAlways talk aboutDNA going in the 5’ to 3’ direction?
Deoxyribonucleotides
What is dideoxyadenosine triphosphate (ddATP)?
Why are dideoxynucleotides useful in Mol.Bio.?
