DNA
 What
it stands for?
 Where is it found?
 Structure of a nucleotide
 Names of the 4 Bases
 Replication of DNA (semi
conservative)
DNA → Gene


A section of DNA will code for a
particular protein. This section is
referred to as a gene.
The section of DNA that codes for
the production of the channel protein
involved in cystic fibrosis is called

Alleles




Alleles are copies of the same
gene.
They can be dominant or
recessive.
We can predict the outcome of
offspring (F1, F2 etc..) by doing
a genetic cross.
Offspring can be homozygous or
heterozygous
