DNA Hybridization
SACCONE POWERPOINT
DNA Hybridization shows that the Red
panda & the Giant Panda are related as
a result of convergent evolution.

Genetic Code
• A genetic code contains the
information for the sequence of amino
acids in a particular protein
• This code is present in mRNA
molecules and is three bases long.
• This is known as a codon
Ex: UAG - is a codon

Messenger RNA (mRNA)
1. When portions of DNA molecules
unwind and separate, RNA
nucleotides pair with complimentary
bases on the DNA strand. This forms
a mRNA that is complimentary to the
DNA strand
2. The sequence of nucleotides in the
mRNA contain the genetic code
3. The genetic code for each amino acid
is a sequence of three nucleotides
forming a codon

Messenger RNA (mRNA)
1. Example:
Here the mRNA is complimentary to
the DNA.
1. The DNA serves as the original
template.
